... In a later stage, we are going to see that F = 0 is required for a particle to be in equilibrium, but it is not sufficient to make that particle in equilibrium since we know that forces could create momentum which will tend to rotate the particle. In the coming lectures, moments about a point or a ...

... Centripetal force means “center seeking” force. It is the force that keeps an object in its uniform circular motion. We determine this force by using Newton's second law of motion, Fnet = ma, where Fnet is the net force acting on the object (this is the centripetal force, Fc, of an object in uniform ...
