According to Newton's third law of motion, the action and reaction forces are
- a)not equal in magnitude and opposite in direction
- b)not equal in magnitude and same in direction
- c)equal in magnitude and same in direction
- d)equal in magnitude and opposite in direction
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
According to Newton's third law of motion, the action and reaction...
Explanation:When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.To every action there is always opposed an equal reaction or the mutual actions of two bodies upon each other are always equal and opposite in direction.

Understanding Newton's Third Law of Motion
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This principle is fundamental in understanding the interactions between objects.
Key Concepts of Action and Reaction Forces
- Equal in Magnitude: The action and reaction forces are always equal in strength. This means that if one object exerts a force of 10 Newtons on another, the second object exerts a force of 10 Newtons back on the first.
- Opposite in Direction: While the forces are equal in magnitude, they act in opposite directions. For example, if Object A pushes Object B to the right, Object B pushes Object A to the left with the same force.
Real-World Examples
- Walking: When you walk, your foot pushes backward against the ground (action), and the ground pushes your foot forward (reaction). This allows you to move.
- Rocket Propulsion: In a rocket, gases are expelled downward (action), and the rocket is pushed upward (reaction). This principle enables rockets to launch into space.
Conclusion
Understanding Newton's Third Law is crucial in various fields of physics and engineering, as it explains how forces work in pairs. The correct answer, option 'D', emphasizes that action and reaction forces are equal in magnitude and opposite in direction, which is fundamental to the motion of objects.
