CONCEPT:

• Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by any external force.
• Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force i.e.,

​ \(F = \frac{{dp}}{{dt}}\)

Where F = force applied, m = mass of the body, and a = acceleration produced.

• Newton's Third Law of Motion states that 'To every action, there is an equal and opposite reaction'.

EXPLANATION:

• The launching of a rocket illustrates Newton’s third law of motion. Therefore the option 1 is correct.
• Newton's Third Law of Motion states that 'To every action, there is an equal and opposite reaction'.
• So, when the rocket is ignited, it releases gases from its thrusters thereby creating a force that will push rocket upwards and it can gain extreme velocity using this principle.

• Newton's third law of motion is applicable irrespective of the nature of the forces. The forces of action and reactions may be mechanical, gravitational, electric, or of any other nature.
• Action and reaction always act on different bodies. If they acted on the same body, the resultant force would be zero and there could never be accelerated motion.
• The forces of action and reaction cannot cancel each other. This is because action and reaction, though equal and opposite, always act on different bodies and so cannot balance each other.
• No action can occur in the absence of a reaction.
