Question

explain newton's 2 law of motion in brief

Answer 1

the rate of change of momentum of an object is proportional to the net force applied on the object,in the direction of net force

Answer 2

According to the Newton's second law of motion,the rate of change of momentum (mass * velocity) is directly proportional to the external force applied in a body
and kg m/s square = newton
one newton is that much force which produces acceleration(change in velocity) of 1m/s square in a body of 1 kg
I tired to make it simple on page ( photo)
so it will help you to understand it easily
