Answer:
The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force. In the example above F = mg = (20 kg)(9.8 m/s2) = 196 N, W = (196 N)(1.5 m) = 294 Nm. Work is a scalar, a number with units.
hope it helps you dear ✌️✌️✌️
