An Integrated Form of F=ma The impulsemomentum (IM) equation is a reformulation—an integrated form, like the workenergy equation—of the equation of motion, F=ma mv12 Fdt = mv Initial Linear Momentum Final Linear Momentum Particle ImpulseMomentum Equation = mv1 = Fdt = mv2 "Impulse" Important!Solution Formula F =ma m= F/a m=N/2ms‾² m=10 kg 2 How much force is needed to prevent a body of mass 10 kg from falling? Example 92 Which would require a greater force –– accelerating a 2 kg mass at 5 m s –2 or a 4 kg mass at 2 m s −2 ? Physics Formulas Examples Solutions Videos Notes F=ma formula example
