MOMENTUM AND IMPULSE Study Guide
What is the formula for momentum?
P= my
2.
If you increase mass or velocity what happens to momentum?
3.
The greater the mass or velocity, is, the greater it's momentum.
If a 2,0009000 kg object is sitting still what is its momentum?
4. What is the law of conservation of momentum? What does it apply to?
The momentum of a system before an event is equal to momenturn afterward.
5.
What causes an increase or decrease in momentum?
or
- the mass and velocity either increase
decrease.

What is an elastic collision? What is an inelastic collision?
Elastic Collision- A collision where objects bounce off each other undamaged.
Inelastic Collision - collide
A collision where objects bounce off, and each is damaged or objects
and stick together..

10. What is impulse, and the formula for impulse?
- A force applied over a time interval.

11. What must happen for an objects momentum to change?
An unbalanced force causes a change in
Acceleration.
12. An object with a mass of 30 kg is moving with a velocity of 6 m/s. What is the
objects momentum?
P=MV
m = 30 kg
P= 30 *6= 180 kgmls
V= 6 m /s
13. A basketball has 25 kg m/s of momentum when thrown 30 m/s. Find the mass of the
basketball.
Pemu
M =
30 = 0.8icg
P=25 kgm/s
V= 30 m /S
14. A 70 kg object has 320 kg m/s of momentum. How fast is the object going?
320= 4.6m/s
P=MV
V = mi
P= 320 kgm/s
m= Mokg
