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

A 1500 kg racecar goes at a constant speed of 96 km/h round a curved section of track that has a radius of 80 m.

1. What is the speed of the car in m/s?

2. What is the car’s centripetal acceleration?

3. What is the centripetal force acting on the car?

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
