... Momentum is conserved in any collisions as long as external forces are negligible. Collisions are classified as elastic or inelastic based on whether the kinetic energy is conserved, meaning whether it is the same before and after the collision. ...

Solution Week 73 (2/2/04) Chain on a scale First solution: Let y be
... Second solution: The normal force from the scale is responsible for doing two things. It holds up the part of the chain that already lies on the scale, and it also changes the momentum of the atoms that are suddenly brought to rest when they hit the scale. The first of these two parts of the force i ...

Chapter 7 Momentum and Impulse
... "How a force changes the motion of an object depends on both the size of the force and how long the force acts. "The right side of the equation is the change in the momentum of the object. "The momentum of the object is the mass of the object times its velocity. ...
