Question

what is newton second law of motion​

Answer 1

Newtons second law of motion:-

The rate of change of a body is directly proportional to the resultant external force acting on the body and takes place in the direction in which the force acts is called Newtons second law.

Formula:-

F= ma

F = Force

M= mass

A = acceleration.

As the force acting upon an object increased then the acceleration the object increased.

As the mass acting upon an object increased then the acceleration of the object decreased.

Answer 2

Newton's second law of motion states that the rate of change of momentum of a body is directly proportional to the applied force

$\mapsto \sf{F \propto \frac{ \triangle p}{t} } \\ \\ \sf \mapsto F = \frac{ \triangle p}{t}$

Where , k is proportionality constant which is equal to 1

$\sf \mapsto F = \frac{mv - mu}{t} \\ \\\sf \mapsto F = \frac{m(v - u)}{t} \\ \\ \sf \mapsto F = ma$

$\therefore \underline{\sf F = \frac{ \triangle p }{t} = ma}$
