Fizzle Main Page. Return to the Intermediate Level Page.  Every
moving object has momentum. Momentum (denoted as p) is just the
product of the mass and velocity: p = mv  If a force is applied
to an object, the product of the force and the time during which
the force was applied is called the impulse. Impulse (denoted at
J) is given by the equation: J = FDt  Now, force is mass times
acceleration. Isn't the change in velocity acceleration times
the change in time? Thus: J = Ft = mat = mv = p (Equation 1-13)
So impulse turns
