Question

Formula of 1st,2nd and 3rd law of motion

Answer 1

First law of motion describes us The inertia hence no formula of my knowledge (I am just a kid)
Second law of motion describes us acceleration and deceleration of real objects means f=ma whereas f is force and it means mass of an object times it's acceleration.

Third law of motion is you know for every action there is an equal and opposite reaction and then we can term the action and reaction as Force hence: F = -F
