Detailed explanation-1: -Newton’s second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.
Detailed explanation-2: -Newton’s Second Law: F = ma, where F is the net force acting on an object; m is its mass and a is its acceleration. Note that both F and a are vectors and must point in the same direction.
Detailed explanation-3: -Newton’s second law of motion states that “Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.
Detailed explanation-4: -The acceleration of an object is directly proportional to the net force and indirectly proportional to the object’s mass (a = f/m).
Detailed explanation-5: -Second law of friction: Friction does not depend on the area of contact between the object and the surface.
