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

1) A rock of mass 250 g is
attached to the end of a 1.5 m
long string and whirled in a
horizontal circle at 15 m/s.
Calculate the centripetal force
and acceleration of the rock.
