Question

1. ____ force is the force that keeps an object moving on a curved path that is directed inward toward the center of a rotation.

a) potential
b) human
c) centrifugal
d) centripetal

Explanation:

The question is about identifying the force that keeps an object moving on a curved path directed inward toward the center of rotation. Centripetal force is defined as the force acting on a body moving in a circular path that is directed toward the center around which the body is moving. Potential force is related to stored energy, human force is not a standard physics term for this concept, and centrifugal force is an apparent outward - directed force in a rotating frame (not the inward - directed force for circular motion). So the correct force is centripetal.

Answer:

d) Centripetal
