Here's why:
* Force: A push or pull that can change an object's motion.
* Distance: The amount of space an object moves.
Work is done when a force causes an object to move a certain distance.
Key points:
* Direction matters: The force must be applied in the same direction as the object's movement for work to be done. Pushing a wall doesn't do any work because the wall doesn't move.
* Work is measured in joules (J): One joule of work is done when a force of one newton moves an object one meter.
