2. The product of the average force applied to an object and the time interval over which it acts, given by.
5. In an isolated system where no external forces act, the total momentum remains constant over time.
9. Forces exerted by objects within a defined system on one another; these do not change the total momentum of the system.
10. A collision where momentum is conserved, but kinetic energy is lost
13. A collision where both total linear momentum and total kinetic energy are conserved.
14. A vector quantity representing the rate of change of displacement.
15. A measure of an object's resistance to acceleration (inertia) and the amount of matter it contains.

1. States that the impulse applied to an object is equal to the change in its linear
3. Forces exerted on a system from outside its boundaries, which cause a change in the system's total momentum.
4. A push or pull acting upon an object resulting from its interaction with another object.
6. A process where an internal force causes a single object to break into multiple parts; momentum is conserved.
7. The standard SI unit for linear momentum and impulse.
8. The product of an object's mass and its velocity, defined by the equation.
11. Usually stated as, but more fundamentally defined as the rate of change of momentum:
12. Vector quantity defined as the product of an object's mass and its velocity
