The force that keeps an object moving in a circle is called a. centripetal force b. fluid friction c. inertia d. momentum

Centripetal force

Explanation:

The object that keeps an object in a circle is called uniform circular motion. In this type of motion, the distance covered by an object is equal to the circumference of the circle. The mathematical form of centripetal force is given by,

From second law of motion,

F = m × a

a is the centripetal acceleration

So, the correct option is (a) '' centripetal force''.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
