IMPULSE & MOMENTUM Flashcards
It is a product of the object’s mass and velocity.
Momentum
What kind of quantity is momentum?
vector
Momentum will always have the opposite direction of the velocity. True or False.
False (same)
It also refers to the amount of motion.
Momentum
It is the change in momentum.
Impulse
“If there is no external force that is applied to a system, then the total linear momentum of that system remains constant in time.”
Law of Conservation of Momentum
“In time, if two objects collide, the total momentum of the two objects before and after the collision should not change.”
Law of Conservation of Momentum
“If there is no external force that is applied to a system, then the total linear momentum of that system remains_________ in time.”
constant
It is the negative ratio of the relative velocity between the objects after collision to before collision.
Coefficient of Restitution
