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 a measure of how much energy is transferred when a force causes an object to move.
Key points about work:
* Direction matters: The force must be in the same direction as the 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): 1 Joule is the amount of work done when a force of 1 Newton moves an object 1 meter.
Example:
Imagine you lift a heavy box from the floor to a shelf. You're applying a force upward, and the box moves upward, so you've done work.
