What is centripetal force? From where does the moon get the centripetal force required for it's motion around the earth?
Answers
Answer:
centripetal is a force which can rotate a body in a cilcure path . f=mv
⏩ Centripetal force:- When a body moves along a path with a uniform speed, its direction of motion changes at every point. The change in direction involves the change in velocity or acceleration. The force that provides this acceleration and keeps the body moving along the circular path, acts towards the centre. This force is called the centripetal (centre - seeking) force. Thus, the force required to make a body move along a circular path with uniform speed is called the centripetal force. It always acts along the radius and towards the centre of the circular path. As shown in the attachment above, it is the centripetal force which continuously deflects a particle from its straight line path to make it move along a circle.
For moon's circular motion around the earth, it needs a centripetal force. This centripetal force is provided by the gravitational attraction exerted by the earth on the moon.
