Detailed explanation-1: -Newton’s second law of motion is F = ma, or force is equal to mass times acceleration.
Detailed explanation-2: -The second law states that the acceleration of an object is dependent upon two variables-the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
Detailed explanation-3: -Force Equals Mass Times Acceleration: Newton’s Second Law.
Detailed explanation-4: -Newton’s Second Law: Force His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.
Detailed explanation-5: -Figure 1: Newton’s second law of motion expressed in components for each direction. The sum of the projection of all forces along the x-axis equals the mass times the acceleration along the x-axis. The sum of the projection of all forces along the y-axis equals the mass times the acceleration along the y-axis.
