Answer»

Workis said to bedonewhen an object moves (displaces) along the direction of application offorce." OR Theworkis defined asforcedisplacement. W = F x S

Types of workPositive workWhen a spring is stretched, the work done by the stretching force is positive as the force acts in the direction of displacement of the spring.

negative work The work done against friction is negative as the frictional force is always in direction opposite to displacement.

zero workA person carrying a load on his hand and walking on a horizontal road does no work as the force is acting at right angle to displacement.
