Definitions
Momentum is...
the property of a moving object that makes it difficult to stop.
A direct relationship is
both variables will go up or down (move in the same direction )
True or false: the claim of a justification provides the elaboration, or explanation, of the problem.
FALSE
the equation used to solve for momentum is...
p=mv
How old is Mrs. Bullerman
23
A symbol is...
the letter used to represent a variable
For example, p for momentum
An indirect Relationship is
Variables will go opposite directions
This section of your justification requires numerics, observations, or facts used to create your claim.
EVIDENCE
The equation used to solve for velocity is....
What is the label used for velocity?
v=P/v
m/s
November 2
an inelastic collision is...
a collision between two objects were momentum is conserved, but KE is not
Velocity and speed are similar because they are calculated as distance over time. How are they different?
Velocity requires a direction... It is a vector.
How many parts of a Justification are need to be COMPLETE?

Ziggy is running a 400 meter dash. He has a recorded momentum of 50 kg*m/s, and has a velocity 5m/s, what is Ziggy's mass?
m = 10 kg
Mrs. Bullerman taught at what school before NFV?
Postville
an elastic collision is...
a collision between two object where both momentum and KE are conserved
If the mass of an object doubles while velocity remains constant, what happens to momentum?
It doubles: one goes up the other goes up = direct
True of False: A Justification is used to organize evidence collected to identify relationships or answer questions.
TRUE
Veronica and her friend Melissa are racing cars and seeing how collisions affect their paths. Veronica 5 kg car is released at 10 m/s. Melissa's 7 kg car is released at 15 m/s. After they collide, only Veronica's velocity was recorded at 12 m/s. Using your knowledge of the Law of Conservation of Momentum, determine was Melissa's final velocity was.
Mrs. Bullerman's husband's name is...
Tayton
Kinetic energy is defined as...
the energy of a moving object, measured in J
What would happen to the mass if momentum is held constant and velocity increases? WHAT IS THE RELATIONSHIP?
DECREASE --> INDIRECT RELATIONSHIPS
What is the formula for the REASONING section of a Justification?
CLAIM + EVIDENCE + ADDITIONAL INFORMATION (they why, the how, etc.)
Two monster trucks are racing towards each other. They both are moving towards each other with a momentum of 25 kg*m/s. The total KE recorded was 400J. After the collision, one truck ends with a momentum of 15 kg*m/s and the other at 35 kg*m/s. The final KE recorded was 250J. What is the collision type?
INELASTIC
KE is not conserved, momentum is adhered to
