P1 - Conservation Of Energy

Question 1

What is the equation for energy transfer/work done?

Answer 1

Work done (J) = Force x Distance

Question 2

What is the equation for Change in gravitational potential energy store?

Answer 2

GPE (J) = Mass x Gravitational field strength (N/kg) x change of height

Question 3

What happens to the gravitational potential energy of something when it goes up?

Answer 3

It increases

Question 4

What is the equation for kinetic energy?

Answer 4

KE = 1/2 x mass x speed^2
