Then Bruce recalled that the ball originally had stored energy as it sat on the wall. This stored energy is called

as the ball fell.
The stored energy that Bruce recalled is called potential energy. Sharon explained that this potential energy was converted into kinetic energy as the ball fell.
The stored energy that the ball originally had while sitting on the wall is called potential energy. Sharon explained that this potential energy transformed into kinetic energy as the ball fell.
Then Bruce recalled that the ball originally had stored energy as it sat on the wall. This stored energy is called potential energy. Sharon explained that this stored energy is converted to another form of energy, known as kinetic energy, as the ball fell.
Potential energy is the energy that an object possesses based on its position or condition. In the case of the ball on the wall, it had potential energy due to its elevated position. The amount of potential energy an object has depends on its mass, height, and the acceleration due to gravity.
To calculate the potential energy of an object, you can use the formula:
Potential Energy (PE) = mass (m) × gravity (g) × height (h)
Here, mass (m) refers to the weight of the object, gravity (g) is the acceleration due to gravity (approximately 9.8 m/s² on Earth), and height (h) is the vertical distance of the object from a reference point (in this case, the ground).
When the ball falls, the potential energy is converted into kinetic energy. Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity. The formula to calculate kinetic energy is:
Kinetic Energy (KE) = 1/2 × mass (m) × velocity (v)²
Here, mass (m) is the weight of the object, and velocity (v) is the speed at which it is moving.
So, the ball initially had potential energy while sitting on the wall, and this energy was converted to kinetic energy as it fell down.
