We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

In the Olympic event of Short Track Speed Skating, athletes race around a rather short track (thus the name of the event) that only has a circumference of 111 meters. It always seems almost magical ...

Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

Newton's first law can also be used to explain the movement of objects travelling with non-uniform motion. This includes situations when the speed changes, the direction changes, or both change. For ...

6.In uniform circular motion, the centripetal force acting on an object is: (a) Parallel to the motion of the object. (b) Perpendicular to the motion of the object. (c) Opposite to the motion of the ...
