Momentum & Impulse
Vocabulary
| Term | Definition |
|---|---|
| Momentum | vector that is a moving mass; how difficult it is to stop something |
| Conservation of Momentum | law that states the total momentum of two objects is the same before vs. after a collision |
| Impulse | change in momentum, caused by a force being applied for a certain amount of time |
| Elastic | collision where objects bounce off each other; total kinetic energy is conserved |
| Inelastic | collision where objects stick together, total kinetic energy decreases |
| Explosion | "collision" where objects are stuck together and then separate, total kinetic energy increases |
| Energy Transformation | energy is neither created nor destroyed, but transformed into other types |
| Conservation of Kinetic Energy | when the total amount of KE is the same before vs. after a collision |
| Impulse-Momentum Theorem | amount of momentum gained in a collision must be the same amount lost by another object (equal & opposite impulses) |
| Newton's 3rd Law | forces between two interacting objects are equal and opposite of each other |
| Internal | forces that are found within a specific system of interacting objects (0 work) |
| External | forces that are outside of a specific system of interacting objects (+ or - work) |
| Thermal | type of energy that is "produced" from friction in a collision |
| Sound | energy in the form of waves "produced" from some collisions |
| Vector | variable that has both magnitude and direction |
| Magnitude | size or amount (number) |
