P1 : Gravitational Potential Energy Flashcards
1
Q
Gravitational Potential Energy
A
The energy an object has due to being raised above the ground. The greater the height on an object above the ground, the greater the GPE it will have, the greater the gravitational field strength, the greater the GPE
2
Q
What is the GPE on earth
A
9.8 N/Kg
3
Q
What is the formula for GPE
A
Ep = m x g x h
Gravitational potential energy (Ep) measured in joules (J)
Mass (m) measured in kilograms (kg)
Gravitational field strength (g) in newtons per kg (N/kg)
Height above the ground (h) in meters (m)
