Detailed explanation-1: -By using momentum change: The formula to calculate impulse through momentum change is by calculating the mass of the body and the velocity. In this case, Impulse will be equal to the product of mass and velocity. So J= m*v.
Detailed explanation-2: -The object’s change in momentum is equal to the impulse it experiences. The formula is F • t = m • v . The product of an object’s mass and velocity determine its change in momentum.
Detailed explanation-3: -The Impulse Momentum Calculator uses the formula Ft = mv, or force F multiplied by the change in time t equals mass m times the change in velocity v.
Detailed explanation-4: -As mass is constant during free-weight resistance training, a greater impulse will result in a greater velocity. Therefore, as generation of force greater than the weight of the resistance increases (i.e. propulsive force; Garhammer and Gregor, 1992) higher movement velocities and/or decreased movement times result.
