ENERGY CONVERSIONS: Energy conversions - KE & GPE No Friction

In our course, all of the KE is converted into GPE and vice versa.

So that means if a book falls from a table to the floor. Its maximum KE will equal the GPE it started with?

• True

• False

Our course WE ASSUME that converts all the KE into GPE and vice versa.

But in real life, the following energy transformation occurs as a ball falls:

• the ball's mass and speed

• the ball's mass, speed and the effect of gravity

• the ball's speed and the effect of gravity

• we cannot do this calculation

• the ball's mass and speed

• the ball's mass, speed and the effect of gravity

• the height the ball was dropped from and the effect of gravity

• the height the ball was dropped from
