Is the change in Momentum the same number as Impulse?

YES!!!!!!

100

This is the product of an object's mass and velocity. 

What is momentum?

100

m is the variable for 

What is mass?

200
If you decrease the velocity does the momentum increase or decrease?
Decrease
200
If the force increases then what happens to the impulse?
It increases
200

What is the end momentum subtracted by the begining momentum?

What is Impulse or the change in Momentum?

200

This is defined as a change in momentum. 

What is impulse? 

200

This is the unit for momentum.

Is Momentum and Impulse a scalor or a vector?

What is Vector?

300

This law states that the total momentum of a system remains constant. 

What is the Law of Conservation of Momentum?

A .25kg marble is rolling on the floor at 2m/s, what is the momentum?

.5Ns or .5 kg x m/s

400
If a 2N force is aplied on an object for 10 seconds what is the Impulse
20Ns
400

If the change in momentum is 10kgm/s, then what is the Impulse?

What is 10Ns?

400

This is the product of the force applied to an object and the amount of time the force is applied. 

What is impulse?

400

This is the unit for impulse. 

What is Newton-Second (N*s)?
500

If you increase the momentum does the mass or velocity increase? 

It could be either

If you increase the impulse, does the force or the time change?

It could be either

500

What causes the Momentum to change?

What is Impulse?
