If the greatest potential energy is 100J will the kinetic energy of the object ever reach 100J?
let's use a block. When a block is released from its rest place on a table, it has:
Potential Energy = 100J
Kinetic Energy = 0
when a block is falling halfway down, it has:
Potential Energy = 50J
Kinetic Energy = 50J
when a block is falling just before it hits the ground, it has:
Potential Energy = 0
Kinetic Energy = 100J
