Linear Momentum

Question 1

When two different masses collide, the response to these forces would be _________________.

Answer 1

Not equal; ie. velocity

Question 2

What is Momentum?

Answer 2

“Quantity of motion”; product of an object’s mass and velocity

Question 3

What is the equation for momentum?

Answer 3

p=mv (units: kg*m/s); vector quantity

Question 4

If two masses (M/m) collide, the forces of impact would be ______________.

Answer 4

Equal and opposite

Question 5

What does the area of a F vs t graph represent?

Answer 5

Δp=FΔt

Area= impulse

Question 6

What is the Law of Conservation of Linear Momentum?

Answer 6

Total linear momentum of a system remains constant despite other changes within the system; momentum is conserved

Question 7

Momentum is ____________ conserved.

Answer 7

Always

Question 8

What is the equation for the momentum of two object with initial velocity in an elastic collision?

Answer 8

M1V1+M2V2=M1V3+M2V4

Question 9

What is the equation for momentum of two objects, one with initial velocity and one at rest?

Answer 9

M1V1=(M1+M2)V2
