Any force that causes an object to move in a circle is called an?
A
balanced force
B
gravitational force
C
centrifugal force
D
centripetal force
Explanation: 

Detailed explanation-1: -Centripetal force is the name given to any force which causes a change in direction of velocity toward the center of the circular motion. The component of the force which is perpendicular to the velocity is the part resulting in the centripetal force.

Detailed explanation-2: -As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.

Detailed explanation-3: -Centripetal force may be considered the center-seeking force.

Detailed explanation-4: -Circular motion requires a net inward or “centripetal” force. Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.

Detailed explanation-5: -The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve.
