Impulse
The change in momentum of an object due to the application of a force over a period of time.
Linear Momentum
The product of an object's mass and its velocity, representing the quantity of motion in a straight line.
Impulse-Momentum Theorem
States that the impulse acting on an object is equal to the change in its momentum.
Conservation of Linear Momentum
The total linear momentum of an isolated system remains constant if no external forces act on it.
Internal Forces
Forces exerted between objects within a system that cancel out due to Newton's Third Law.
External Forces
Forces exerted on objects by sources external to the system, which can affect the system's momentum conservation.
Collisions in One Dimension
Events where the total momentum of isolated systems is conserved, with examples like elastic, inelastic, and completely inelastic collisions.
Collisions in Two Dimensions
Collisions within isolated systems conserve momentum components in both x and y directions.
Center of Mass
The point representing the average location of the total mass of a system, with a velocity that remains constant in an isolated system.
