Here's a breakdown:

* Work is done when a force causes an object to move a certain distance.

* Force is a push or pull that can change an object's motion.

* Distance is the amount of space an object moves.

Key point: For work to be done, the force must be applied in the direction of the object's motion. If the force is perpendicular to the motion, no work is done.

Formula:

Work (W) = Force (F) x Distance (d)

Example:

If you push a box across the floor with a force of 10 Newtons and move it 5 meters, the work done is 50 Joules (10 N x 5 m = 50 J).
