Which is true about centripetal force and centripetal acceleration?
|
|
The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force is always pointing outward
|
|
|
The centripetal acceleration is always pointing outward from the center of an orbit and the centripetal force is always pointing inward
|
|
|
The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force also pointing toward the center but in a totally different location
|
|
|
The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force also pointing toward the center and in the same exact location as the centripetal acceleration
|
Explanation:
Detailed explanation-1: -Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r; ac=r2.
Detailed explanation-2: -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. This is sometimes referred to as the centripetal force requirement.
