if a force acts on a body whose action line does not pass through its center of gravity, then the body will experience
Correct answer: A. angular acceleration
- A. angular acceleration
- B. linear acceleration
- C. no acceleration
- D. none of these
Explanation
If a force acts on a body whose action line does not pass through its CG, the torque created by the force will cause the body to experience angular acceleration. This means the object will start rotating, even if it also experiences some linear acceleration depending on the specific direction and magnitude of the force.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
