A couple produces:
Correct answer: B. Purely rotational motion
- A. Purely linear motion
- B. Purely rotational motion
- C. Linear and rotational motion
- D. No motion
Explanation
A couple is a system of forces with equal magnitude, parallel lines of action, and opposite directions, but not acting along the same line. When a couple is applied to an object, it creates a torque, which results in rotational motion. The object will experience rotation without any translational motion.

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.
