You are swinging a tennis ball attached to a 55 cm long cord, swinging the tennis ball in a circle. As you swing the tennis ball, the force of tension in the cord keeps the tennis ball in a circular path. The mass of the tennis ball is 0.25 kg, and as it swings around, speed of the tennis ball is 3.8 m/s. What is the force of tension in the cord? (the unit of force is the 'Newton' )

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.
