Test Chapter 9 Flashcards
1
Q
Momentum
A
The product of the objects mass and the objects velocity
2
Q
Impulse momentum theory
A
The impulse on an object is equal to the objects final momentum minus the objects initial momentum
F*t= pf-pin (p=mv)
3
Q
Closed system
A
A system that does not gain or lose mass or energy
4
Q
Isolated system
A
A closed system on which the net external force is zero
5
Q
Law of conservation of momentum
A
States that the momentum of any closed , isolated system does not change
6
Q
Impulse
A
Product if the average net force and the time interval over which the time acts f*t
