What is work in physics?
What is work in physics?
When a force causes an object to move a certain distance.
Is work done when you push a box across the floor?
Is work done when you push a box across the floor?
Yes, work is done because a force is applied (pushing) and the object is moving (displacement).
Is work done when you push a heavy box that doesn't move?
Is work done when you push a heavy box that doesn't move?
No, work is not done because the box is not moving. Even though you're applying a force, there's no displacement.

Study Notes
Work
- Work is the product of force and displacement in the same direction
- Conditions for work:
- Force must be present
- Displacement must occur
- Force and displacement must be in the same direction
- Units of work: Joules (J)
- Formula for work: W = F × d
- Where:
- W = Work
- F = Force
- d = Displacement
- Where:
