Work done:
- The dot product of force and displacement is called work done.
- SI unit of Work is Joules.
- Work done is given by,
Work done (W) = F.s cos θ _____(1)
Where,
F is force
s is displacement
θ is the angle between F and s.
EXPLANATION:
As we know that Work done (W) = F.s cos θ _____(1)
∴ Force = mass × acceleration
The dimensional formula of force (F) = [MLT-2]
The dimensional formula of displacement (s) = [L]
Put the values of force and displacement in equation (1) neglecting angle,
Work done (W) = F.s
Work done (W) = MLT-2.L
Work done (W) = ML2T-2
∴Dimensional formula of work (W) = [ML2T-2]
