Question

give me notes on newtons 3 laws of motion with example and explanation

Answer 1

first law= a body will not move until and unless the external force will not apply on it
for example = a football will remain rest until the external force will not apply on it
second law = net acceleration is directly proportional to net force
example if we increase the amount of net force than the acceleration also increase in same amount
it stated that when we apply force to anything it will also apply force . for example rocket give force to earth by boosters in against earth also give force which helps rocket to move upward , another example is that when we push wall the wall will not move because wall is also giving force to us

Answer 2

Hi Friend,

Here is your answer,

1st Law:- Every body continous to be of rest or of in it's uniform motion unless it is complled by an external forces.

It defines inertia and force 

Example:- A ball rolling down a hill will continue to roll unless friction or another force stops it.


2nd law:- Rate of change of momentum of a body is directly proportional to the external force acting on it and takes place in the direction of force this gives the measure of force and this is the real law of motion

F= dp/dt

Example:-A fielder pulls his hand backward; while catching a cricket ball coming with a great speed, to reduce the momentum of the ball with a little delay.

3rd Law:- For every action there is an equivalent opposite reaction.

Example:-the piston exerts a force on the bullet to propel it, but the reaction from the bullet causes the piston to move back, taking you along with it.


Hope it helps you!
