What must be true of a force that causes an object to move in a circular motion?

It acts parallel to the velocity and is directed toward the center of the circle.
It acts parallel to the velocity and is directed away from the center of the circle.
It acts perpendicular to the velocity and is directed toward the center of the circle.
It acts perpendicular to the velocity and is directed away from the center of the circle.

Answer:

The correct answer is "It acts perpendicular to the velocity and is directed toward the center of the circle."

Step-by-step explanation:

The centripetal force is the force needed to keep a body moving along a circular trajectory, the direction of the force is given over the length of the radius and toward the center.

When a body moves within a circular path, its velocity at any point on this path is equal to the tangent of the velocity at that point.

Since the centripetal force is perpendicular to the velocity of the body, it is drawn toward the center of the circle that represents the trajectory of the body.

Have a nice day!

Answer:

It acts perpendicular to the velocity and is directed toward the center of the circle.

Step-by-step explanation:

For a force to make an object move in a circular motion, the force must act perpendicular to the velocity and directed toward the center of the circle of motion as shown in the attached image.
