Study Notes
Contact Forces
- A force that acts on a body in a direction opposite to its motion when it slides or rolls over a rough surface is an example of a contact force.
Friction
- Friction is the force that resists the motion of a book on a table top when it tends to move.
- Friction comes into play when there is motion or tendency of motion between two surfaces in contact.
- When a book is placed on a table top and pushed to the right, the direction of the force of friction is to the left, opposing the motion.
