Newton's First Law states that " every object which is at rest or uniform motion continues to be in state of res or uniform motion unless compelled to change its state by action of net force."
Example:A space craft far from any source of gravity would need no thrust to keep it moving at a constant speed in a given direction.Once set in motion, it continues to move forever without propulsion since there is no friction is space.
1st law of motion When a ball is rolled in one direction at certain speed, it will continue to move in the same direction at the same speed until it comes in contact with an obstacle in the opposite direction
Second law of motion " Rate of change of momentum of the body is directly proportional to the force acting on it."
Example:Fielder in a cricket match pulls his hand backwards to reduce impact of impulse force.Working of air bags to prevent the time of injury.Objects in our room remain as it is unless a force as on it act.If we shake a tree, the fruits at rest will fall down.
2nd law of motion It is always easy to move an empty shopping cart around than moving it when it is loaded with the items that you buy at a supermarket.
