Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

If you double the radius of an object in uniform circular motion, how
does its centripetal acceleration change?
O It decreases by a factor of 2.
O It increases by a factor of 2.
O It decreases by a factor of 4.
O Changing the radius does not affect the centripetal acceleration.

As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration.
