Question

A bicycle speeds up as it moves along a flat road. What happens to the bicycle’s gravitational potential energy during this time?

1.It decreases.

2.It increases.

3.It remains the same.

Answer 1

It stays the same since there are no changes in elevation. GPE is given by mgh. Since h remains constant on a flat road, so does GPE

Answer 2

it remains the same because without an uphill or downhill the speed stays the same
