Impulse Momentum Flashcards

Conservation of Momentum

states that the momentum of any closed, isolated system does not change.

Impulse

the product of the average force on an object and the time interval over which it acts

Isolated System

does not allow either energy or matter to enter or leave (no net external force is exerted on the system)

Momentum

when mass is multiplied by velocity (p=mv)

Impulse-Momentum Theorem

states that the impulse on an object is equal to the change in the object’s momentum

Closed System

does not allow matter to enter or leave, allows energy to enter or leave

Elastic Collision

both momentum & kinetic energy are conserved, objects move in opposite directions after collision

Inelastic Collision

only momentum is conserved but not kinetic energy, objects move together after collision

Kinetic Energy

energy due to linear motion

Work-Kinetic Energy Theorem

states that the work done on an object equals the change in energy of the object

Potential Energy

energy that results from the position of an object

Power

the rate at which energy is transformed
