all about friction

1. Frictional force
The force acting along two
surfaces in contact which
opposes the motion of one
body over the other is
known as FRICTIONAL
FORCE

2. The force of friction
exerted by fluids is
known as fluid
friction
FLUID FRICTION

3. TYPES OF FRICTION
Frictional force can be divided
into three types . They are:
Static friction
Sliding friction
Rolling friction

4. Static Friction

5. Sliding Friction

6. Rolling Friction

7. Spring Balance
A device used to measure the weight of
an object
Can also be used for the measurement of
forces

8. Effects of friction
•Friction opposes
motion

9. •FRICTION PRODUCES HEAT

10. Friction causes wear and tear

11. Advantages of friction

12. Disadvantages o f friction
