The point at which an applied force produces linear motion but no rotatory Motion is:
Correct answer: B. Center of gravity
- A. Mid-point
- B. Center of gravity
- C. Optical center
- D. Pole
Explanation
The point at which an applied force produces linear motion but no rotational motion is the "center of gravity." The center of gravity is the point within an object or system where the weight is evenly distributed in all directions. When an applied force is directed through the center of gravity, it results in pure linear motion without causing the object to rotate.When an external force is applied to an object, it causes translational (linear) motion when applied through the center of gravity. However, if the force is applied away from the center of gravity, it can create both linear motion and rotational motion, causing the object to pivot or rotate.The center of gravity is a critical concept in physics, particularly in mechanics and the study of equilibrium. It plays a role in determining stability, balance, and the response of an object to applied forces.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
