Momentum = mass velocity. You can multiply by 5/8 to get it to km/hr and then divide by 3600 to get it to km/s and then multiply by 1000 to get it to m/s, but that would only give you an approximation as a kilometre is not exactly 5/8 of a mile. Easy enough to figure out, as long as you have the principle of conservation of angular momentum under your belt. The key difference between acceleration and momentum is that acceleration refers to the rate of change in velocity of a moving object, whereas the momentum of an object is the product of the mass of the object and its velocity. How do you find momentum in physics? This activity involves the analysis of a collision between a moving cart and a dropped brick that lands on top of it. If an object moves with a double velocity, its momentum doubles. Your email address will not be published. Momentum is a vector quantity; i.e., it has both magnitude and direction. The problem gave us the force of the hammer on the nail, but not the force of the nail on the hammer, which is what we need for the equation as we are looking purely at the momentum of the hammer.
