2 When you ride your bike uphill, where
does the energy you use come from?
A) from the food you eat
B) from the exercise you do
C) from the push of the ground on the
bicycle -
D) from the pull of gravity on you and
the bicycle
The energy is in motion, so it is kinetic energy, and it is derived from the food we digest. At the top of the hill, in the absense of motion, the kinetic energy converts to potential energy.
