Gravitational Potential Energy Flashcards
1
Q
What is gravitational potential energy
A
The energy stored in an object due to its position above the earths surface
This is due to gravity acting on an object

Q
How does cycling uphill affect the maximum speed of this cyclist?
A
maximum speed is lower
because maximum power output of cyclist is constant
(but) additional work is done (against gravity)
or
gravitational potential energy (of cyclist) is increased
