Work Done (J)

Work Done (J)= Force(N) × Distance (Metres)

Weight (N)

Weight(N) = Mass (kg) ×Gravity (N/kg)

Δ in an object's PE

(Change inan object's gravitational potential energy)

Δ in an object's PE= Weight (N) × Δ of height


Δ Gravitational Potential Energy (EP)

ΔEP = Mass (kg) ×gravitational field strength ×

change of height (ΔH)

Kinetic energy (J)

Kinetic energy(J) = 1/2 mass (kg) ×speed squared

(metres per second)

Elastic potential energy, Ee (J)

Ee (J) = 1/2 spring constant ×extension squared

(Newtons per metre) (metres squared)

Efficiency (%)

Useful Output (J) / Total Input ×100

Power (Watts)

Energy (J)/ Time (seconds)

Power wasted

Power wasted= total power in- useful power out
