How many times higher than the original height does the ball bounce?
So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on. Try it yourself! Does f depend on the height? (it shouldn't much, but it might..) Try it for different balls! which type of ball bounces the most ? which kind of ball bounces the most ?
How do you measure bounce height?
Specifically, it is proportional to the fraction of the height that the ball bounces compared to the height that the ball is dropped. The students drop balls from a meter height and determine how high they bounce. They record and repeat the process five (or 10) times, rounding to the nearest cm (or 5 cm depending on the resolution desired).
Do golf balls bounce higher than tennis balls?
Tennis balls bounce about 53% of their dropped height, Super Balls about 85 or 90 % of their dropped height. I've never tried golf balls; why don't you try one and let us know.
How Bouncy is a basketball on wood?
For a properly inflated basketball, f is about 0.75. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference.
How high does a golf ball bounce when dropped?
When dropped from any height onto a hard surface, their ball will rebound 0.8 (80%) of the original height, whereas the competitors ball will have a rebound ratio of only 0.7 (70%).
Does the height of a ball drop affect the bounce?
If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
What determines how high a ball will bounce?
When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
What is the relationship between drop height and bounce height?
The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.
Do larger balls bounce higher?
The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.
Does Weight Affect bounce?
In conclusion , this experiment's data shows that the weight of the ball does matter when it comes to bouncing. If its to heavy it won't bounce to high because of its weight. If its to light it won't have enough force to bounce.
Why do golf balls bounce so high on concrete?
Why Do Golf Balls Bounce So High on Concrete? A hard surface like concrete can cause a golf ball to deform slightly and create elastic force. This causes the golf ball to store energy through deforming, and bounce while releasing that energy.
Can a ball bounce higher than from where it was dropped?
The reason it doesn't bounce higher than where it started is simple: some of the ball's energy is lost as heat when it bounces, so it doesn't have as much going up as it did coming down. Knowing that, you might figure that a ball could never bounce higher than the height from which is was dropped.
What factors affect the bounce of a dropped ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Why can't a ball bounce higher than the height from which it is dropped?
The force of the floor pushing against the ball throws the ball back up into the air. The reason it doesn't bounce higher than where it started is simple: some of the ball's energy is lost as heat when it bounces, so it doesn't have as much going up as it did coming down.
How does a surface affect the bounce height of a ball?
A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. A soft surface, like grass or carpet, absorbs more energy from the fall, so there's less left to push the ball back up, and it bounces pretty badly.
When you drop a bouncy ball Why doesn't it return to the height from which it was released?
Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height.
How high does a ball bounce?
Unfortunately there are only two things you will find out about a ball, by bouncing it from a height of about 5 feet . One is, how high it bounces from this height and two, how fast it will come off a putter.
How far does a ball travel without dimples?
The aerodynamics of a ball are extremely important. For example, a ball without dimples will travel about 130 yards compared to an otherwise identical ball with dimples – launched at the same speed, spin, and launch angle – which will travel 260 yards.
What is the energy of a ball?
A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy . After the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise.
What is the F of a superball?
For a superball, f may be around 90% (0.9) or perhaps even bigger. For a steel ball on a thick steel plate, f is >0.95. For a properly inflated basketball, f is about 0.75. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy.
Does the radius of a ball matter?
The radius of the ball doesn't really matter , if you are measuring the height of the ball from the bottom of the ball to the ground. A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy. After the bounce, the ball and ...
What is bounciness in sports?
The bounciness is related to the elasticity of the material or how much it deforms under pressure. Every sport usually uses a different type of ball (tennis ball, basketball, volleyball, golf ball, baseball, ping pong ball).
Do super balls bounce from meter stick?
Inevitably, some students will lose their super balls. Determine your response to this prior to distributing the balls. Some balls may not bounce very true and therefore bounce far from the meter stick, resulting in a wide variety of bounce heights.
