Physics Unit 5: Momentum Flashcards

Front

Elastic collision

Back

A collision between two or more objects where the net kinetic energy is conserved in the system.

Front

Impulse

Back

The quantity of a force applied over a period of time, equal to the change in momentum of an object (Impulse=Force×Time).

Front

Inelastic collision

Back

A collision between two or more objects where some kinetic energy is converted to another form of energy, such as heat or sound.

Front

Law of conservation of momentum

Back

The total momentum of a system remains constant unless a net external force acts on the system.

Front

Momentum

Back

The product of the mass and velocity of an object (Momentum=Mass×Velocity).

Front

Direction

Back

The line or course along which something moves, pointing from one position to another.

Front

Displacement

Back

The straight-line distance and direction between an object's initial and final positions.

Front

Force

Back

A push or pull exerted on an object, causing it to accelerate, decelerate, or change direction, typically measured in newtons (N).

Front

Mass

Back

The measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

Physical system

Back

A defined collection of interacting components that are being studied, isolated from the external environment.
