Define work, power and energy. State their S.I units?

Answer»

Work : The product of magnitude of displacement (S) and component of force (Fcosθ) along the direction of force is called

work. i.e., W =  vector F.S  = F S cos θ.

Unit → Joule;

Power : The rate of doing work by a force is called power.

P = w/t, Unit → watt (or) J/S

Energy : The capacity to do work is called energy.

Unit → Joule
