# Newton’s Law of Motion

### Newton’s Third Law – concepts and examples

Newton’s Third Law Newton’s third law of motion states that To every action there is an equal and opposite reaction. This means for every action or force that acts on an object, there is a reaction force that is equal in magnitude and opposite in direction to the action force. And this reaction force acts on a

### Momentum and Impulse: Getting the Impulse Momentum Theorem

Momentum While playing some sort of body-contact game, if we are pushed by a heavy but slow moving person, we begin to move. Similarly if a lighter person comes with higher velocity and pushes us we may face the same net effect and again begin to move. In physics, these effects can be well explained

### Newton’s First Law of Motion doesn’t hold good for all frames of reference

Newton’s first law of motion and Frame of reference Newton’s first law of motion says that if the sum of all the forces acting on a particle is zero then a static particle continues to remain at rest and a moving one continues moving with a constant velocity along a straight line. That means if no
