Momentum and Its Conservation
Across
- 4. A system which does not gain or lose any mass
- 5. A wheel or a disk that spins rapidly around one axis while being free to rotate around one or two other axes
- 7. States that the momentum of any closed, isolated system does not change
- 13. Velocity, momentum, force, and impulse are all ______ quantities
- 14. Equation for Impulse
- 15. During a _________ two or more objects exert a force on each other
- 18. States that the angular impulse on an object is equal to the object’s final angular momentum minus the object’s initial angular momentum
- 19. Is equal to the product of the average force on an object and the time interval over which it acts
- 20. Equation for Momentum
Down
- 1. States that if no net external torque acts on a system, then the angular momentum is conserved
- 2. Equation for the Angular Impulse-Angular Momentum Theorem
- 3. States that the impulse on an object is equal to the object’s final momentum minus the object’s initial momentum
- 6. A closed system with a net external force of zero
