Formulas and Key Relations

1) Work

W = F × s

1 J = 1 N × 1 m = 1 kg m^2 s^-2

Work done by a constant force = force applied × displacement in the direction of the force

2) Energy and Work-Energy Theorem

Work done on an object = change in its energy

4) Kinetic Energy

K = (1/2)mv^2

W = (1/2)m(v^2 - u^2)

Work = force × displacement in the direction of force.

K = 1/2 mv^2.
