NEWTON’S THIRD LAW OF MOTION

NEWTON’S THIRD LAW OF MOTION
I hope you all enjoyed in learning about Newton's law of motion on Newton's first law and second law of motion. Hear i will help you understand more on newton's third law of motion.
The second law relates the external force on a body to its acceleration. What is the origin of the external force on the body ? What agency provides the external force ? The simple answer in Newtonian mechanics is that the external force on a body always arises due to some other body.
Equal and Opposite Force

The forces on the space-shuttle are similar to the forces in a collision between two tennis balls. When the balls collide, they are propelled in opposite directions. The rockets of the space-shuttle force burning gases downward through the exhaust vents. In response to these downward forces, the shuttle system moves upward. The motion of the space-shuttle demonstrates Newton's third law of motion. When one object exerts a force upon a second object, the second object exerts an equal and opposite force upon the first object. The third law of motion states that every action has an equal and opposite reaction. You can see equal and opposite forces interact when you blow up a balloon and release it, it moves in the opposite direction. The force propelling the balloon is equal and opposite to the force of the air leaving the balloon
Have you got an hang on newton's law of force. Keep reading .. let me also share with you on an Experiment on Newtons Third Law .
