Question

EXPLAIN THE THREE LAWS OF NEWTON. PLEASE​

Answer 1

Explanation:

first law is if any body is in the state of rest then it will be remain in the the state of rest and if if the body is in the state of motion then it will be remain in the state of motion

thanks

hope it helps

Answer 2

Explanation:

Newtons 1st law=

Every inanimate object continues to be in its state of rest or of uniform unaccelerated motion unless and until it is acted upon by an external, unbalanced force.

2nd Law=

Rate of change of linear momentum of rigid body is directly proportional to applied force and takes place in direction of the applied force.

F=dp/dt (where F is force and p=mv )

3rd law=

To every action , there is an equal and opposite reaction.

From newtons 2nd law,

F =dp/dt=d/dt(mv)

where mass m is constant ,

therefore,

F=mdv/dt=ma

Thus if F=0 then v is constant,

if there is no force, velocity will not change. This is nothing but it is Newtons 1st law of motion.
