5. The work done on an object is this type of quantity because technically it has magnitude but not a specific direction.
A 100

6. What is a scalar quantity?

7. It acts on an object to displace it during work.

8. What is a force?
A 200

9. When negative work is done, the force acts on an object in the opposite direction to this.

10. What is the object’s displacement?

11. This force does negative work on a filled cardboard box as you try to push it across the floor.

12. What is friction?
A 400

13. This component of the force on the object actually does the work.
