Question

Whenever an object undergoes uniform circular motion, it experiences a net force
A) directed toward the normal.
B) equal to the mass times the velocity.
C) directed toward the center of the circle.
D) equal to mass times velocity divided by the radius of the circle.

Answer 1

Answer:

C) directed toward the center of the circle.

Explanation:

An object undergoing uniform circular motion is an object that is moving at constant speed along a circular trajectory.

According to Newton's Laws, in order to keep the object in circular motion, there must be a net force that keeps changing the object's direction (otherwise, the object would just move in a straight path due to its inertia).

This force is called centripetal force, and it always points towards the centre of the circular path. Its magnitude is given by

$F=m\frac{v^2}{r}$

where

m is the mass of the object

v is the speed

r is the distance of the object from the centre of the trajectory

Answer 2

Answer:

C) directed toward the center of the circle.

Explanation:

Whenever an object undergoes uniform circular motion, it experiences a net force directed toward the center of the circle. The magnitude of this force is represented by the formula [[m$v^{2}$/r]].
