Doc Al, I'm assuming when a torque is applied to a record to make it spin on the turn table that this results in an angular change in velocity, which settles into a constant velocity of 33 and 1/2 rpms. As a result of the constant angular velocity, a centripetal force occurs. I'm trying to...

I'm in the Rotational Motion Chapter. After torque is applied to rotate an object,how do I go about breaking down the tangent vector and the centripetal force vector? What I want to know is how the torque is being divided between the tangent direction and the radius direction.

Newton's Third Law, Conceptual Post When an object collides with another object, the second object exerts and equal and opposite force upon the first. When objects interact, they only do it at the same moment. One object cannot hit another without the other one not hitting it. There is no...

I thought the Earth's velocity changes, due to an elipitical path. But, if it were circular I still have a problem. If I choose one tangent along the circular path in which the Earth moves and measure the speed in that direction as the Earth passes. The next moment, the Earth has changed...

Yes, I mean speed in place of velocity. I will edit it to stop the confusion. Would it be easy to explain, I am only taking conceptual physics. So, a non-mathematical explanation would be best for me. This is why I can't think of it any other way: In order for a mass to change position...

Is is possible when two objects have one interaction, that one object experience only a change of direction and no change in speed? It seems possible for two objects to have an interaction where there is no change of direction. (Each object has no spin and they are on a co-linear path.)...
