The
direction of the acceleration is towards the centre O of the circle.
This
acceleration is called centripetal acceleration.
Equation
of motion of uniform circular motion
For
uniform circular motion
:
The
direction of the external force is always at right angles to the
direction of motion.
Method
to solve problems concerned with uniform circular motion
1.
Draw a free body diagram
2.
Find out the net
force acting on the object in the radial direction towards
the centre of
the circle
3.
Apply Newton’s second law ( equation of motion ).
Examples
:
Vehicles
going round bends and the conical pendulum :
Looping

At
the top of the loop :
For
non-uniform circular motion :
