Chapter 2.4 Flashcards
1
Q
Linear momentum definition and formula
A
The product of the mass of a body times it’s velocity
p = mv
2
Q
Newton’s second law in terms of momentum
A
F = change in momentum over change in time
3
Q
Impulse
A
The product of the average force times the time for which the force acts
4
Q
What is the area under the curve of a force time graph?
A
Impulse
5
Q
Law of conservation of momentum
A
When the net force on a system is zero the momentum does not change
6
Q
Elastic collision
A
When kinetic energy is conserved
7
Q
Totally inelastic collision
A
When the maximum possible kinetic energy is lost
8
Q
Kinetic energy in terms of momentum
A
KE = p^2/2m
