Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Is there a simple way to do block, pulley and inclined plane problems? What are the gotchas when doing them?

Expert Solution

Step 1

There are several types of problems in physics. Block pulley problem is one of them. These problems have several tricks to solve.

Step 2

Before solving such kind of problems, there is some important points which should be kept in mind to make these problem simple.

Step 3

If two blocks are connected with one rope on inclined plane, then tension in rope will be same. If block is moving in one direction, then the net force will be in moving direction.
