Force-Centrifugal Force and Inertia
... Ok, I would like to discuss with you force, inertia, and centrifugal force. Now, the definition of force is any influence that causes a free body to undergo a change in speed, change in direction, or a change in shape. So, you have change in speed, direction or shape. So that’s the definition of a f ...
