If the direction of an applied force F is reversed, then

Correct answer: A. The object will accelerate in the opposite direction.

  • A. The object will accelerate in the opposite direction.
  • B. The object will remain stationary.
  • C. The object's speed will increase.
  • D. The object will continue moving in the same direction.

Explanation

When a force is applied to an object, it causes the object to accelerate in the direction of the force. If the direction of the applied force F is reversed, the object will accelerate in the opposite direction. This occurs because the force vector changes direction, impacting the object's motion accordingly. Option A is correct as it captures this effect. Options B, C, and D do not accurately describe the physical impact of reversing the direction of a force on an object's motion.

About Newton's Laws of Motion

Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
