Question

Physics 1

One of the main topics this week is circular, or centripetal, motion looking at its acceleration and associated force. For the centripetal force, is this a NEW force, explain?

Often times, CENTRIFUGAL force is used in describing circular motion, is this an appropriate alternative to centripetal force, explain?

One example of centripetal force is its application to curves - flat & banked - in terms of the maximum speed one can make the curve, what happens when the coefficient of friction changes (up & down)? What happens in each case if friction is lost? Did you find the observation surprising? Intriguing?

Answer 1

During circular motion any force which act toward center is called centripetal force.

For examples .if a stone is moving by attaching thread to one of its end so Here TENSION force will be consider as centipital ,

When moon moves around earth here gravatinal force is centripetal...

Remember cenrtpital force is not the fundamental force of physics ...any force which act toward center can be consider as cenrtpital force .It is not new force.

Now ,when we observed circular motion from INERTIAL Frame then this is called centripetal force when same force observed from NON INERTIAL frame then this is called centrifugal force ..
