How do you calculate the momentum of a golf ball?
Let's calculate the momentum of the golf ball in the above example. If the golf ball has a mass of .05 kg, and a velocity of 15 m/s, then what is its momentum? (Answer: momentum= .05 kg*15 m/s= 0.75 kg m/s)
How does force affect the speed of a golf ball?
In a collision, the amount of time the golf ball is in contact with the club and/or the amount of force applied will cause the object to speed up or slow down. Newton's Third Law: The impulse (the force times how much time the force is applied) will cause the golf ball to speed up or slow down.
What happens to a golf ball in a collision?
In a collision, the amount of time the golf ball is in contact with the club and/or the amount of force applied will cause the object to speed up or slow down. The impulse (the force times how much time the force is applied) will cause the golf ball to speed up or slow down.
What causes a golf ball to travel in the air?
This collision causes the ball to travel into the air. In a collision, the amount of time the golf ball is in contact with the club and/or the amount of force applied will cause the object to speed up or slow down. The impulse (the force times how much time the force is applied) will cause the golf ball to speed up or slow down.
What is the change in momentum of the golf ball?
So, we can see that the golf ball has gone from having a momentum in the positive direction to having no momentum at all, which means that this negative change in momentum does make sense. Our final answer, then, is that the change in the ball's momentum is equal to negative 0.009 kilogram-meters per second.
What causes a greater change in momentum?
The momentum change is dependent upon the velocity change; the object with the greatest velocity change has the greatest momentum change.
Which ball has the greatest change in momentum?
Explain? The ball that bounces has a GREATER change in momentum being that the numerical value is larger.
How is momentum applied in golf?
Impulse changes the momentum of an object. It increases the speed of a golf ball when the time of contact between the golf ball and club is increased. The longer the contact time between the golf ball and the club, then the greater the velocity of the golf ball and the further it will travel.
What is momentum affected by?
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
How can you increase the momentum of an object?
If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
What is a change in momentum?
The change in momentum is a difference in motion. When an object is in motion, strikes, or collides with another object, the exerted force accelerates an object by varying its motion. The change in momentum is calculated using the Impulse formula or conservation of momentum.
Which object would have the most momentum?
more massive objectThe momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.
Which of the following have the largest momentum?
EXPLANATION: Momentum is directly proportional to the mass and velocity of an object. A greater velocity implies more momentum. Hence, a car driving on a highway with high velocity will have the greatest momentum.
What are the forces acting on a golf ball?
Some of these forces include: gravity, aerodynamic drag, and aerodynamic lift. Each force acts independently on the moving golf ball. For a greater distance to be achieved, one needs to increase the acceleration of the ball by increasing the force with which the ball is struck or swinging the club faster.

Control is due to something in physics called rotational inertia a scientific principle that says the farther an object's mass is away from the axis of rotation the harder.
How are Newton's laws of motion applied in golf?
Newton's 3rd law states with every reaction, there is an equal and opposite reaction. As the golf club comes down at the bottom of the swing, the club head comes in contact with the golf ball at a certain force, as they come in contact, the force of the club on the ball is equal to the force of the ball on the club.
What happens if your center of mass is right up next to the ball?
If your center of mass is right up next to the ball, you will not have room to get your mass in motion and stay in motion all the way through impact, while also allowing you to have full extension of your arms with the feeling of a full release in your golf swing. This is the first fundamental concept you will lean when taking ...
How to do a squat in golf?
Step 1: Without a club, pick out a target and start walking towards it, while in stride turn 180 degrees right with your back facing the target and continue moving towards it, then turn back to the left with the front of your body once again facing the target.
What happens if you turn left before dropping your shoulders?
Drop the shoulders and arms (If you start turning left before the shoulders have dropped, they will start pulling you out of balance and there will be an involuntary pull that will not let you continue moving towards your target smoothly and will most often cause a shot that starts left and the continues to draw farther off that line).
How to walk without a golf club?
Without a club, pick out a target and start walking towards it, while in stride turn 180 degrees right with your back facing the target and continue moving towards it, then turn back to the left with the front of your body once again facing the target. You should be able to stay walking on a straight line, even though you are turning back and forth. It may help to put a tee in the ground and walk towards it so that you get an idea of how straight your line is.
Can you hook a ball if you don't get far enough forward?
The funny thing is, as long as your body is moving forwards, there is not ever a problem with a hook. Because even if you don’t get far enough forwards with your mass at impact, but it is still moving in that direction, the ball starts a little left and go straight.
How Do Golf Ball Dimples Work?
Any object moving through the air faces the force which the air exerts on it. There are two components to the force an object flying through the air undergoes:
How Do Golf Ball Dimples Improve the Game?
Now that you understand at least a bit of the aerodynamics involved with golf ball dimples, you can look at how exactly this appears in an average round of golf. For the player, golf ball dimples serve two purposes:
Have Golf Balls Always Had Dimples?
Golf has been around for a long time, and for a lot of that time, people played with smooth balls. However, at some point in the 1800s, players noticed that their dented golf balls actually performed better than the perfectly smooth ones.
Are All Golf Ball Dimples the Same?
After learning how vital dimples are to a golf ball’s success, you may be surprised to learn that golf ball dimples are not regulated. They can have different shapes, different depths and appear in varying amounts on balls.
Golf Ball Dimples Are Not Everything
There are other things that go into how smoothly and how far a golf ball flies beside the dimples.
Conclusion
Two key forces affect your golf ball’s flight: drag and lift. Golf ball dimples have a massive impact on both, which is why they are so crucial for effective golf balls. Dimples reduce drag and increase lift.
Take Action – What You Can Do Today to Get Better
What does this mean for you? I believe in the following recipe to get better:
From Observation to Mathematical Model
As a child, I occasionally would walk around a nearby golf course with my family on rainy days; the only times when no golfers would dare to play. Our own game was to find lost balls from previous, unfortunate players. The person who found the most balls would win.
The Drag Crisis Observation
Throughout history, the flows around many different shapes have been studied by scientists. For example, vortex streets are generated by the flow around cylinders. Although a sphere does not generate this type of large alternating flow structure, the flow characteristics can also be linked to the Reynolds number.
The Reason for the Drag Crisis
First of all, let’s recall that the drag of an object is caused by two sources:
Modeling the Aerodynamic Forces of Golf Balls
Now we understand why golf balls have dimples in the first place. Let’s remember that the drag is lower and therefore the ball can go further. To find out how much further the ball can go, we first need to compute its trajectory.
Finding the Optimal Launch Angle
The effect of the dimples on a golf ball should now be clear: They make the ball go further. However, in practical terms, this does not say much about how I should hit the ball.
Conclusion
In today’s blog post, we answered a seemingly simple question about golf ball dimples, which has to do with the behavior of the turbulent boundary layer over a sphere at a specific range of Reynolds numbers. This also outlines a classical process in engineering.

What happens when a golf ball hits a ping pong ball?
When the golf ball strikes the floor, it bounces up and collides with the ping-pong ball. This action transfers the greater momentum of the golf ball to the ping-pong ball, which responds by rising faster and higher.
What is momentum in sports?
In the engineering and physics world, momentum refers to the quality of motion that an object has, and it depends on the mass and velocity of the object:
How does momentum relate to collisions?
The amount of momentum an object has depends both on its mass and how fast it is going. For example, a heavier object going the same speed as a lighter object would have greater momentum. Sometimes, when objects collide into each other, momentum can be transferred from one object to another. There are two types of collisions that relate to momentum: elastic and inelastic. In a closed system, which means that there are no external forces acting on the objects that collide, both types of collisions follow the Law of Conservation of Momentum, which states "the total amount of momentum before a collision is equal to the total amount of momentum after a collision."
How to calculate momentum?
After this lesson, students should be able to: 1 Calculate the momentum of a moving object. 2 Recognize that momentum is proportional to mass and velocity. 3 Explain that in a closed system, momentum is conserved in both elastic and inelastic collisions. 4 Describe how collisions and momentum play an important role in the design of safe automobiles.
What is the law of conservation of momentum?
In a closed system, which means that there are no external forces acting on the objects that collide, both types of collisions follow the Law of Conservation of Momentum, which states "the total amount of momentum before a collision is equal to the total amount of momentum after a collision.".
Why do engineers consider momentum when designing vehicles?
In a head-on collision, the front end of a car is designed to crumple, making the collision inelastic. It takes energy to crumple the front of the car and this is what absorbs some of the impact.
Why do engineers use crumple zones?
A crumple zone is designed into motor vehicles to absorb the main impact of the energy being transferred during a crash, so the people inside don't get hurt.
