Force Formulas 21/9/20

Question 1

What is the work done formula?

Answer 1

work done = force (Newtons) x distance moved (metres)

Question 2

Gravitational potential energy formula

Answer 2

GPE (joules) = mass (kg) x gravitational field strength (N/kg) x change in height (meters)

Question 3

Kinetic energy formula

Answer 3

KE = 0.5 x mass (kg) x velocity squared (m/s)

Question 4

Elastic energy formula

Answer 4

Epe= 0.5 x spring constant (N/m) x extension squared (meters)
