Calculate and record the Gravitational Potential Energy of the golf ball for heights of 0.50 m, 1.00 m, and 1.50 m using the formula: PE = mgh (mass = Kg g = 10 m/s2 = meters PE = Joules) 3. Drop the golf ball from the same height 5 times, record the rebound height after the ball hits the floor. Average the results of the five trials.

How can I calculate the potential energy lost by a ball?
To find the % potential energy lost, I will use this equation: (h1-h2) / h1 * 100. where h1 = initial height ball is dropped from; h2 = rebound height of ball. 3. The attempt at a solution. My prediction is, that as the initial height the ball is dropped from increases, the percentage PE (potential energy) lost by the ball will also increase.
What happens to potential energy when a ball hits the ground?
Since the ball will be falling, the gravitational potential energy will be converted into kinetic energy + energy dissipated as heat into surroundings (due to friction/air resistance) Stage 2: Just before the ball touches the ground, the ball will have the following properties:
What happens to kinetic energy when a ball is dropped?
My prediction is, that as the initial height the ball is dropped from increases, the percentage PE (potential energy) lost by the ball will also increase. I think this is the case because at a higher height, the ball will have more PE. This will then all be converted to KE (kinetic energy) as the ball falls.
How do you find the potential energy of an object?
How to calculate potential energy. The easiest way to calculate gravitational potential energy is to use our potential energy calculator. This tool estimates the potential energy on the basis of three values. These are: The mass of the object. Gravitational acceleration, which on Earth amounts to 9,81 m/s².
What is the potential energy of a falling ball?
As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface. When the ball collides, the kinetic energy is transformed into other forms of energy.

How do you find the potential energy of an object?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Does a golf ball have potential energy?
When you hold a golf ball high above the ground, it's full of energy. But it's all gravitational potential energy (stored energy) that's waiting to transform into kinetic energy (moving energy) as soon as you drop it.
What energy is used when hitting a golf ball?
When a club hits it, the ball will gain kinetic energy and travel in the same direction the club was moving. The larger the force of the club, the bigger the impact and the faster the ball will go. So the size, shape, and mass of a golf club really matter when it comes to transferring energy and force to the ball.
How do you calculate energy transferred?
The energy transferred can be calculated using the equation:E = P × t. Where: E = energy transferred in joules (J) P = power in watts (W) ... E = I × V × t. Where: I = current in amperes (A) V = potential difference in volts (V) ... E = Q × V. Where: Q = charge in coulombs (C) V = potential difference in volts (V)
What happens to the energy of the ball and the Earth when they collide?
If the collision between the ball and the Earth is perfectly elastic then the mechanical energy of the system will be stored as elastic (spring) potential energy when the ball and the Earth deform during their collision. Then that elastic potential energy will be converted to kinetic energy of the ball and Earth but now they are moving away ...
Why does the ball gain momentum?
Each also gain kinetic energy but the ball will gain much more kinetic energy than the Earth because the mass of the ball is so much smaller than the mass of the Earth.
What happens when you drop a bowling ball?
Conservation of energy when dropping a ball [duplicate] Closed 2 years ago. If we drop a bowling ball from one meter above the earth's surface, we are converting its gravitational potential energy to kinetic energy. When it hits the floor, it transfers its kinetic energy to the earth, so now the earth is moving directly downward at a larger ...
What happens when you drop a bowling ball from one meter above the Earth's surface?
If we drop a bowling ball from one meter above the earth's surface, we are converting its gravitational potential energy to kinetic energy. When it hits the floor, it transfers its kinetic energy to the earth, so now the earth is moving directly downward at a larger (but imperceptible) speed.
How does the Earth bounce back?
With a bouncing ball, the Earth does bounce back, but gradually slows down attracted by the ball and stops when the ball also stops as it reaches its initial height. If the Earth is hit by a meteor, the resulting speed will depend on the mass and speed of the meteor when it was far away from the Earth. If the meteor was not moving, but gained its ...
Can the ball and Earth be at rest?
Not so. Consider the ball and the Earth as an isolated system with both initially at rest and then let the ball fall down towards the Earth. If there are no external forces acting on the system the total momentum of the ball and Earth system must be zero for all time.
Does the ball have potential energy?
It is the ball and the Earth which have the gravitational potential energy not the ball alone. When it hits the floor, it transfers its kinetic energy to the earth, so now the earth is moving directly downward at a larger (but imperceptible) speed. Not so. Consider the ball and the Earth as an isolated system with both initially at rest ...

What happens when a ball comes into contact with the ground?
When the ball comes into contact with the ground, some energy will be lost as heat and sound (the sound of the ball contacting the ground). Stage 3: The ball will rebound. Just after the ball rebounds, the ball will have the following properties: Gravitational Potential Energy is minimum (~ 0)
What is the key to energy transfer?
The true key to energy transfer? The HANDS SLOW DOWN or STOP for impact. The clubhead has to move three to four times the distance the hands move. Hands must slow down or stop at impact for the clubhead to catch up to the hands and for the transfer of energy to release from the body to the ball.
Why do golfers slice the ball?
Many golfers fail to slow down the hands for energy release and, as a result, they usually slice the ball. This is often because they believe they must swing the hands fast to get distance . They cannot believe that actually slowing down the hands releases energy to the ball.
How do good golfers get maximum distance?
Good golfers appear to get maximum distance by swinging easy, effortlessly and slowly. Good golfers use the science of energy transfer. From high school, we learned that energy cannot be created; nor can it be destroyed. Energy can only be transferred from one state to another. When hitting a golf ball, energy from the body must be transferred ...
Is it true to slow down the swing?
People say, “slow down the swing,” but this is not entirely true; the accurate statement should be to slow the hands, or stop them for a split second, for impact. Slowing the swing down can often help this, but the proper hand action must prevail.
Can energy be destroyed?
As earlier stated, energy cannot be created; nor can it be destroyed. Energy can only be transferred from one state to another, from body to ball. The large amount of energy created in the body transfers to the smaller mass of the ball for violent and strong energy action — and maximum distance and direction.
