Energy Equations

Question 1

Elastic (potential)energy

Answer 1

E(joules)=1/2 x force (newtons) x extension of the spring (meters)

Question 2

Gravitational (potential) energy

Answer 2

E(joules)=mass (kg) x gravitation field strength (n/kg) x height (meters)

Question 3

Kinetic energy

Answer 3

E(joules)=1/2 mass (kg) x velocity to the power of two (meters per second)
