Momentum Vocabulary
Question | Answer |
---|---|
Physical system | A system of 2 or more objects in which momentum is conserved during interactions of the objects. |
Momentum | A vector quantity defined as the product of an object's mass and velocity. |
Impulse | The product of the force and the time over which it acts on an object. Also change in momentum. |
Collision | An event in which 2 or more bodies come together. |
Elastic Collision | A collision in which the total momentum and total kinetic energy remain constant. |
Inelastic Collision | A collision in which the total kinetic energy of the colliding particles is not the same after the collision as before it. |
Perfectly inelastic collision | A collision in which two objects stick together and move with a common velocity after colliding. |
Law of Conservation of Momentum | The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects. |
