please explain newton's third law of motion! 

Statement of Newton’s third law
To every action there is always an equal and opposite reaction
This law explains that the force occurs in pair i.e. whenever there is an action there is always an equal and opposite reaction. Suppose if you pull an object then the object has a tendency to pull with an equal force in a direction opposite to the direction of applied force.
Example: Rocket- gas system-The rocket is propelled in upward direction because of the action-reaction principle.  
Hope this helps,
Good luck.

newton's third law is-  "Every action has equal and opposite reaction"                                                                                                                                                                this statement means if we do some work  we get some profit  for example if we study well we get more marks so according to how much we studied that many marks we every action has equal and opposite reaction

A force is a push or a pull upon an object that results from its interaction with another object. Forces result from interactions! As discussed in Lesson 2, some forces result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) and other forces are the result of action-at-a-distance interactions (gravitational, electrical, and magnetic forces). According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is:

For every action, there is an equal and opposite reaction.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

A variety of action-reaction force pairs are evident in nature. Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. But a push on the water will only serve to accelerate the water. Since forces result from mutual interactions, the water must also be pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on the water (backwards) is opposite the direction of the force on the fish (forwards). For every action, there is an equal (in size) and opposite (in direction) reaction force. Action-reaction force pairs make it possible for fish to swim.

Hi ...!!

According to Newton's third law of motion ,To every action there is an equal and opposite reaction.

Eg :When a person walkson the ground,he pushes the ground with his foot in the backward direction.This is the action.According to Newton's third law,an equal and opposite reaction acts on the foot of the person by the ground.This is the reaction and it helps the person to move forward. 

hope dis helps u ...!!

 Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries, and can be summarized as follows:

  1. First law: The velocity of a body remains constant unless the body is acted upon by an external force.[3][4][5]
  2. Second law: The acceleration a of a body is parallel and directly proportional to the net force F and inversely proportional to the mass m, i.e., F = ma.
  3. Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear.

The three laws of motion were first compiled by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica, first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.
