momentum and inertia Flashcards
1
Q
momentum formula
A
P=MV
mass x velocity
2
Q
what does momentum suggest
A
any object will keep moving until a force is applied
momentum is constant
changes in momentum will only happen following a change in velocity, because mass is constant
3

an objects resistance to change its state of motion
4
