Formulas

Question 1

What’s a formula for kinetic energy

Answer 1

Kinetic energy(Ek)= 0.5 x mass(kg) x speed squared (m/s)

Question 2

What is the formula for gravitational potential energy

Answer 2

Gravitational potential energy(J) = mass(kg) x gravitational field strength(N/Kg) x height(m)

Question 3

What’s the formula for power if work is done

Answer 3

Power(W) = work done (J) divide by time (s)

Question 3

What is the formula of power when energy is transferred

Answer 3

Power (W) = energy transferred(J) divide by time(s)
