2. Outline
• About circular motion
• Types of circular motion
• Example of circular motion
• Formulas used in circular motion
• Conclusion

3. Definition
• Circular motion is a movement of an
object along a circular path.
• Circular motion always rotate about
a fixed point O.
O

4. Types of motion
• Non uniform circular motion
An object is moving in a circular path
with a varying speed.
Constant centripetal force but object
will have a variable circular motion.
Direction of acceleration vector vary
from center.
There are two types of circular motion
• Uniform circular motion
When the motion of the object is at a
constant speed.
Object will complete repeated stripes
in the same amount of time.

5. Examples of Circular Motion
1. Uniform circular motion The acceleration is
always directed
toward centre.
The motion is at
constant speed
Ferris wheel

6. 2. Non uniform circular motion
The net acceleration is no longer
pointing toward the centre
Tangential
acceleration
Centripetal
acceleration
NET acceleration

7. Formulas
r
Angular frequency (W) = rate of change
of angle theta
Angular velocity (V)= W multiply by
radius (r)
Centripetal acceleration (a)= W²r or
WV or V²/r
Centripetal force (F)= mWr or m(V²/r)
or mW²r

8. Conclusion
• Circular motion is a movement of an object along a circular path.
• We have uniform and non uniform circular motion
