3. What is Friction
• Friction is an external force that opposes the relative motion of two
contact areas.
• Friction occurs at the point of contact between the two bodies.
• Relative motion occurs whenever one item travels relative towards
another.

4. Type of Friction
Friction is the force that opposes the motion of a solid object over another.
There are mainly four types of friction:

5. Advantages Friction
•Friction enables us to walk freely.
•It helps to support ladder against wall.
•It becomes possible to transfer one form of energy to another.
•Objects can be piled up without slipping.
•Breaks of vehicles work due to friction.

6. Disadvantages Friction
•Friction produces heat which damages the moving parts of a
machine.
•Friction produces wear and tear on the contacting surfaces.
This reduces the life of machine parts, tyres and shoe soles.
•A lot of energy is wasted due to friction to overcome it before
moving.

7. CONCLUSION
 Friction is caused when two surfaces in contact slide over
each other.
 Factors contributing to friction include the coefficient of
friction (μ) and the normal force.
 Friction always opposes the motion and acts in the
direction opposite to the applied force.
