Question

What are the three laws of Isaac Newton

Answer 1

NEWTON'S LAW

1ST LAW states that:
a body in state of rest will remain in rest or a body in the state of motion will remain in motion until and unless any external force is applied on it

Example: when bus suddenly starts movie we fall backwards.. this is due to inertia of rest

2ND LAW : it states relation between force acting on a body and it's mass and acceleration...
i.e. F=ma

Example: if we push a truck and a school bag then the acceleration of school bag will be much more than the acceleration of truck as mass of truck is much more than the mass of school bag

3RD LAW: every action has equal and opposite reaction.

Example: for walking on road we push the road and as a result of which road exerts same force on us but in opposite direction as a result of which we are able to move forward...

Answer 2

1. According to Newton's first law of motion ,if a body is in a state of rest ,it will remain in the rest and if it is in the state of motion ,it will remain moving in the same direction with the same speed unless an external force is applied on it.

2. According to Newton's second law of motion ,the rate of change of momentum of a body is directly proportional to the force applied on it and the change in momentum takes place in the direction in which the force is applied.

3. Third law : To every action there is always an equal and opposite reaction.
