Equations - Energy

Question 1

Kinetic Energy

Answer 1

Ek = 0.5 x M - Mass (Kg) x v2 - speed (M/s) (squared)

Ek = Kinetic Energy (J)

Question 2

Elastic Potential Energy

Answer 2

Ee = 0.5 x K (Spring constant - N/m) x e2 (Squared)

Question 3

Gravitational Potential Energy

Answer 3

Ep = M (Kg) x G (9.8 N/Kg) x H (m)

Question 4

Change in thermal energy

Answer 4

AE (J) = m (Kg) x c (J/Kg/Degree)x A0 (Degrees)

Question 5

Work done

Answer 5

Work done (J) = Force (N) x Distance (m)
