Here's a breakdown of the key elements:
* Force: A push or pull that can change an object's motion.
* Movement: The object must actually change its position.
* Direction: The force must have a component in the direction of the object's movement.
Formally, the definition of work is:
Work = Force x Distance
Important points to remember:
* Work is a scalar quantity: It only has magnitude, not direction.
* Work is measured in joules (J): 1 joule is equal to 1 Newton-meter.
* If there is no displacement, no work is done. For example, pushing against a wall doesn't result in work because the wall doesn't move.
* Work can be positive or negative:
* Positive work is done when the force and displacement are in the same direction. Think of lifting a box.
* Negative work is done when the force and displacement are in opposite directions. Think of lowering a box.
