As per BBC,

• Work done is defined as a product of the force and the distance over which the force is applied.
• Work is done when a force is applied to an object and the object is moved through a distance.
• For example, when you lift a load you are applying a force over a distance so you are doing work.

As per iCoachMath

• Work is said to be done when an object moves (displaces) along the direction of application of force.
• OR The work is defined as force displacement.
• W = F x S
As per Wikipedia
• In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.
• For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
• Work transfers energy from one place to another, or one form to another.
Work done is defined as a product of the force and the distance over which the force is applied. Work is done when a force is applied to an object and the object is moved through a distance.

Work done:
= force x distance.
= W = F x d.
• W is measures in joules.
• F is measure in newtons.
• d is measured in metres.
• When work is done, energy is transferred.
