KE and PE particle intro
Kinetic Energy and Potential Energy of a
Particle in a Gravitational Field
Imagine a ball, or particle in a gravitational field like the one below. Now imagine that particle is released and travels in a path towards the "ground" (the bottom of the simulation window). Think about the Kinetic and gravitational potential energy of the particle before it is released, during its path down and after it is released, and try to answer the questions below. Remember that the total energy of the particle is equal to the kinetic energy plus the gravitational potential energy. The collision with ground is elastic.
A particle in a gravitational field
When the particle is released, the gravitational force pulls it down toward the ground.

true
When the particle is farthest from the ground
When the particle is half way to the ground
Just before the particle hits the ground
The gravitational PE never changes, it remains constant
