Explain me multiple acceleration
Hello,
To my knowledge there are three types of acceleration when a body (e.g. a rod) is moving in a circle about an axis. These are:
-
Angular acceleration : this is the rate of change of angular velocity.
-
Tangential acceleration : this is the linear acceleration of the system in a tangential direction to the circle and equals the radius times the angular acceleration.
-
Radial/centripetal acceleration : this is the linear acceleration of the system that is directed inwards towards the center of the circle
Hope this helps...
