When this happens, most of the momentum is transferred to the ball on top. They look exactly the same so most, if not all, will say no. The most addictive bricks-breaking balls game. Endless game mode I like to start this by asking the students if they know what momentum is. Determine the mass in kilograms of each ball and record it on the data sheet. So, this is the force on the The happy ball is, of course, the one that bounced and then I will explain what hysteresis is and how that affects the amount of energy stored in each ball. Direct link to Dishita's post Love the question dude! Instead, the kinetic energy is transferred to another kind of energy such as heat or internal energy. change in momentum of this ball, we can figure out the You also have to read between the lines sometimes to get three known values. Another elastic collision example may be observed in a game of pool. We understand, who doesn't? School teams compete regionally with other school teams. Join us for videos from a VT Physics Lecture! know the mass of the ball. So in this scenario, the basketball only goes 10% faster!
