Newton's law of motion -
1 - First law: If there is no net force on an object, then itsvelocityis constant. The object is either at rest (if its velocity is equal to zero), or it moves with constant speed in a single direction.[2][3]
2 - Second law: Theaccelerationaof a body isparalleland directly proportional to the netforceFacting on the body, is in the direction of the net force, and is inversely proportional to themassmof the body, i.e.,F=ma.
3 - Third law: When a first body exerts a forceF1on a second body, the second body simultaneously exerts a forceF2= F1on the first body. This means thatF1andF2are equal in magnitude and opposite in direction. Means, " every action has an equal and opposite reaction"....
