Chapter 8 Flashcards
1
Q
Momentum
A
inertia in action
2
Q
momentum formula
A
p=mv
3
Q
units of momentum
A
kg*m/s
4
Q
inertia
A
the tendency of mass to resist movement or a change in its movement
5
Q
impulse
A
the quantity force * time interval, change in linear momentum
6
Q
bouncing
A
impulses are greater when an object bounces
7
Q
why is the impulse greater when bouncing?
A
the impulse required to bring an object to a stop and throw it back is greater than the impulse to stop
8
Q
change in momentum
A
exert an impulse on it
9
Q
collisions
A
momentum is conserved in all
10
Q
inelastic
A
objects stick together, KE is not conserved
11
Q
elastic
A
moving objects stop, resting object moves, KE is conserved
12
Q
A
