Angle between action and reaction forces is:
Correct answer: C. π rad
- A. 0o
- B. π/2 rad
- C. π rad
- D. 2π rad
Explanation
Option C is correct. According to Newton's third law of motion, every action force has an equal and opposite reaction force. This means they are in a straight line but pointing in opposite directions, creating an angle of 180 degrees or π radians. Option A (0 degrees) is incorrect because the forces are not aligned in the same direction. Option B (π/2 radians) is incorrect because the forces are not perpendicular. Option D (2π radians) is incorrect as it represents a full rotation, which does not apply to the linear relationship of action and reaction 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.
