Question

what is 2nd law of motion​

Answer 1

Answer:

The first law has already given us a qualitative definition of force. Now we are interested in finding out its magnitude. According to Newton’s second law of motion, the net force experienced by a body is directly proportional to the rate of change of momentum of the body. It can be written as:

Newton's Second Law

f∝dPdt⇒f∝mv−mut⇒f∝m(v−u)t⇒f∝ma⇒f=kma

Where k is the constant of proportionality and it comes out to be 1 when the values are taken in SI unit. Hence the final expression will be,

F = ma

Answer 2

Answer:

a=F/m

Explanation:

the acceleration of a body is determined by the Mass of the object and force acting oni it
