Question

The force that keeps an object moving in a circle is called

A. Centripetal force
B. Fluid friction
C. Inertia
D. Momentum

Answer 1

A. Centripetal force
(I think)

Answer 2

Centripetal force

Step-by-step 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

`F=(mv^2)/(r)`

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