Answer 1

Answer:

Newton's second law of motion State that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system,and inversely proportional to it's mass.. if the only force acting on an object is due to gravity, the object is in free Fall

Brother, I hope that you have got the answer to this question from my side and you have understood it.

thanks me latter

Answer 2

The rate of change in momentum is directly proportional to the applied force.

$i.e. \: F∝ \frac{mv - mu}{t}$
