Momentum Notes

Momentum Notes

By Whitney Ratliff

Momentum is defined as: mass in motion. All objects have mass; so if an object is moving,

then it has momentum.

​

Momentum:

1.What are the two variables that effect momentum?

2. momentum a scalar or vector quantity?

3.What will stop an objects momentum?

4. How can we manipulate the force equation into the impulse equation?

5. what is the conservation of

momentum?

6. What is an isolated system?

7. How can we derive an equation represent the conservation of momentum?

7. How can we derive an equation represent the conservation of momentum?

8. What are real world applications of the conservation of momentum?

9. What are the 3 types of collisions?

10. What are elastic collisions?

11. What happens when two objects

collide and stick together?

12. Why are inelastic

collisions the most common?

Multiple Choice

2 balls collide and bounce off of each other. During the collision total momentum remained constant and total kinetic energy remained constant. What type of collision is this?

• Inelastic Collision

• Elastic Collision

• Perfectly Inelastic Collision

• No collision occurred

Multiple Choice

A BMW rear ends a car at the stop light. Neither car sticks together. The momentum was conserved in the collision but the kinetic energy was not conserved. What type of collision is this?

• Elastic Collision

• Inelastic Collision

• Perfectly inelastic Collision

• No Collision

Multiple Choice

Two metal balls collide in an elastic collision. Is momentum conserved in this collision?

• Yes

• No

Multiple Select

What two variables effect momentum?

• mass

• weight

• height

• Velocity

Multiple Choice

What is the equation for momementum?

• $$p=m\times v$$

• $$p=m\times a$$

• $$p=f\div a$$

• $$m=p\times v$$

Multiple Choice

What word can best describe the total momentum in an isolated system?

• constant

• large

• lost

• low

Multiple Select

Pick all of the scenarios below that are collisions.

• A catcher catches a baseball.

• A pitcher throws a baseball.

• Two cars smash into each other.

• Two students on roller skates push away from each other.

• A bug smashes into a windshield.

Multiple Choice

The definition of momentum is

• Mass in Motion
• The size of an object
• The velocity of an object
• A comparison between two objects
