momentum Flashcards
1
Q
definition of momentum
A
product of mass and velocity
2
Q
formula
A
momentum= mass x velocity
3
Q
unit
A
kg m/sec
4
Q
factors affecting momentum
A
- mass of object (momentum ∝ mass)
- velocity of object (momentum ∝ velocity)
5
Q
impulse
A
change in momentum
force x time
6
Q
law of conservation of momentum
A
for an isolated (no forces inside/outside) system, momentum before collision = momentum after collision
7
Q
define resultant force
A
change in momentum per unit time
