In your own words explain why the force and acceleration vectors in Uniform Circular Motion point inward. Also discuss the differences between Centripetal Force and Centrifugal Force.

Solutions

Expert Solution

An object moving in a circle is experiencing an acceleration. Even if moving around the perimeter of the circle with a constant speed, there is still a change in velocity and subsequently an acceleration. This acceleration is directed towards the center of the circle. And in accord with Newton's second law of motion, an object which experiences an acceleration must also be experiencing a net force. The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.

comparison between Centripetal and Centrifugal Force

Differences Between Centripetal And Centrifugal Force
Centrifugal Force	Centripetal Force
If an object moving in a circle and experiences an outward force than this force is called the centrifugal force	If the object travels in a uniform speed in a circular path is called centripetal force.
The object has the direction along the centre of the circle from the centre approaching the object	The object has the direction along the centre of the circle from the object approaching the centre.
Mud flying of a tire is one example of the centrifugal force.	A satellite orbiting a planet is an example of the centripetal force.

The electric field of the wave is given by E = Eo[cos(kz - wt)x - sin(kz - wt)y]. Note that at z=0, where the electron moves, this electric field is E = Eo[cos(wt)x + sin(wt)y].
