Momentum And Impulse Flashcards
What is linear momentum
The product of an object’s mass and velocity
What is Newton’s second law of motion in terms of momentum
The net force acting on an object is equal to the rate of change in momentum of the object
What is impulse
The product of the net force on an object and the time interval for which it is applied
When does momentum change
When a net force is applied
What is the law of conservation of momentum
The total linear momentum of an isolated system remains constant
What is an isolated system
A system in which the net external force acting on the system is zero
What is an elastic collision
A collision where the total kinetic energy before the collision is equal to the total kinetic energy after the collision
What is an inelastic collision
A collision where the total kinetic energy of a system before the collision is not equal to the total kinetic energy of a system after the collision
