Linear Momentum Flashcards
When two different masses collide, the response to these forces would be _________________.
Not equal; ie. velocity
What is Momentum?
“Quantity of motion”; product of an object’s mass and velocity
What is the equation for momentum?
p=mv (units: kg*m/s); vector quantity
If two masses (M/m) collide, the forces of impact would be ______________.
Equal and opposite
What does the area of a F vs t graph represent?
Δp=FΔt
Area= impulse
What is the Law of Conservation of Linear Momentum?
Total linear momentum of a system remains constant despite other changes within the system; momentum is conserved
Momentum is ____________ conserved.
Always
What is the equation for the momentum of two object with initial velocity in an elastic collision?
M1V1+M2V2=M1V3+M2V4
What is the equation for momentum of two objects, one with initial velocity and one at rest?
M1V1=(M1+M2)V2
