S is specified to have the same value everywhere on one of these surfaces and a different unique value on each different surface. Newtons second law of motion can be formally stated as follows. To v in the interval of time t This means Initial velocity of the object u.
All movement is of itself along straight lines.
Newtons second law states that the acceleration of an object depends upon two variables the net force acting on the object and the mass of the object. S is specified to have the same value everywhere on one of these surfaces and a different unique value on each different surface. The acceleration produced by a moving body is directly proportional to the force applied over it and inversely proportional to the mass of the object. While the first law defines inertia the second law of motion formula explains the relationship between acceleration and force.
