Newton’s third law of motion does not hold true when action and reaction occur on the same body. Action and reaction pairs always affect different bodies.

Hence, option B is the correct answer.

The initial velocity is 20 m/s since the body is thrown vertically upwards at that speed. Additionally, it will come to rest if thrown upward, so its final velocity is zero meters per second. We will consider acceleration to be -10 m/s² since the gravitational force acts in the opposite direction of motion.

The car is traveling at a constant speed, so its velocity does not change. Acceleration is the change in velocity. There is no change in velocity, so the acceleration produced in a var is zero. So, option C is the correct answer, and all other options are incorrect.

Impulse is a change in momentum. The formula for momentum change is Force into the interaction period, which is essentially a set amount of time. The unit of force is N and the unit of time is s, so the unit of impulse is Ns.

Another possible answer is momentum, but it is important to distinguish between momentum and momentum change.

In contrast to vector quantities, which have both magnitude and direction, scalar quantities only have magnitude.

There are only magnitudes for temperature, density, volume, and speed. But force has both direction and magnitude. It is a vector as a result.

Newton’s third law of motion states that if a ball falls vertically and bounces on the ground, the force it applies to the ground is always equal to the force the ground applies to the ball and in the opposite direction. Option B is therefore accurate.

Since both forces cannot be greater than or equal to one another, all other possibilities are erroneous. For Newton’s Third Law of Motion to be accepted, they must be in opposition to one another.

Deceleration or retardation are terms used to describe the opposite of acceleration or the decrease in acceleration.

As a result, both options A and B are correct. As a result, we will mark Option E as the correct option.

There is no term in physics for negative motion, so option D is incorrect.

A vector that can be moved parallel to itself is called a free vector.
