Q
What is the gravitational potential energy
A
GPE= m x g x h
1
Q
What is the equation for work done
A
Work done= force x distance moved
2
Q
What is the equation for kinetic energy
A
KE = 1/2 x mass x speed^2
3
Q
Falling objects covert GPE into KE
A
Kinetic energy gained = gravitational potential energy lost
4
Q
Principle of conservation of energy
A
the total energy of an isolated system cannot change—it is said to be conserved over time
