# Which of the following is correct about action reaction pair?

## Which of the following is correct about action reaction pair?

Newton’s Third law states that the equal and opposite action-reaction pair acts on different bodies. Hence, the correct option is B. Note: Whenever two bodies interact, they exert equal and opposite forces on each other.

## Are N and Mg action reaction pair?

Gravity, weight and normal force are all different things. The force of gravity, and the normal force, are not an action reaction pair. At first glance it may appear that these are action-reaction pairs because the forces are equal and opposite. However, they are not because both forces are acting on the same object.

## Is normal a reaction force?

The normal force is one type of ground reaction force. If the person stands on a slope and does not sink into the ground or slide downhill, the total ground reaction force can be divided into two components: a normal force perpendicular to the ground and a frictional force parallel to the ground.

## Is friction an action reaction?

For example, a book feels a force of friction as it slides across a table. Those forces are equal and opposite but are not an action-reaction pair! First, both forces act on the same object while action-reaction forces ALWAYS act on different objects.

## Which law of motion is friction?

Newton’s first law of motion states that there must be a cause—which is a net external force—for there to be any change in velocity, either a change in magnitude or direction. An object sliding across a table or floor slows down due to the net force of friction acting on the object.

## Which law of motion is inertia?

Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

## What is the best example of Newton’s first law of motion?

The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton’s first law. The motion of a kite when the wind changes can also be described by the first law.

## What is the first law of Newton?

Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.

## What are the three laws of motion class 9?

In the first law, we come to understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And, finally, the third law states that for every action, there is an equal and opposite reaction.

## What is state of motion class 9?

An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force. All objects resist a change in their state of motion. The tendency of undisturbed objects whether they are at rest or moving with uniform velocity is called inertia.
