GPE & KE Flashcards
1
Q
What is gravitational potential energy?
A
Energy stores in an object due to its position on the Earth’s surface
Due to the force of gravity acting on an object
2
Q
Equation for gravitational potential energy
A
Ep = m x g x h
gravitational potential energy (J) = mass (kg) x gravity (N/kg) x height (m)
3
Q
What is kinetic energy?
A
Energy stored in moving objects
Stationary objects have no kinetic energy
4
Q
Equation for kinetic energy
A
Ek = 0.5 x m x v²
Kinetic energy (J) = 0.5 x mass (kg) x speed (m/s)
