A father swings his child around in a circle. the source of the centripetal force that keeps the child moving in a circle is _____. tension friction weight gravity
Answer:
Tension
Explanation:
Centripetal force for an object in circular motion. It keeps the revolving object in its path. Centripetal force acts along the radius of the circular path.
It is given by:
\(F_c=\frac{mv^2}{r}\)
where, m is the mass of the object, v is its tangential velocity and r is the radius of the circular orbit.
The source of the centripetal force swinging around in a circle is provided by the tension in the arms of the father holding the child. Weight of the child acts downwards.
