a. Which ball has the greater velocity?
b. Which has the greater momentum?
2. Explain why the green ball has more momentum but less velocity than the red ball (HINT: what is the definition of momentum?).

Known Conditions:

1. You are using a simulation with the following settings:
   • 1 dimension
   • Velocity vectors ON
   • Momentum vectors ON
   • Reflecting borders ON
   • Momenta diagram ON
   • Elasticity at 0%
2. You are observing green balls and red balls.

Questions:

Step-by-Step Solution:

a. Which ball has the greater velocity?

• In the simulation, you will need to observe the velocity vectors of both the green and red balls. The length of the velocity vector indicates the magnitude of the velocity. The ball with the longer vector has the greater velocity.

b. Which has the greater momentum?

• Momentum ( ) is defined as the product of mass ( ) and velocity ( ):
• To determine which ball has greater momentum, you will need to consider both the mass and the velocity of each ball. If the green ball has a larger mass than the red ball, it could have greater momentum even if its velocity is lower.

c. Explanation of Momentum vs. Velocity:

• Definition of Momentum: Momentum is a vector quantity that depends on both the mass and the velocity of an object. It is given by the formula .
• If the green ball has more mass than the red ball, it can have more momentum even if its velocity is lower. This is because momentum takes into account both how fast an object is moving (velocity) and how much matter it contains (mass). Therefore, a heavier object moving at a slower speed can have more momentum than a lighter object moving faster.

Conclusion:

• To answer the specific questions, you will need to observe the simulation directly. Look at the velocity vectors to determine which ball has the greater velocity and calculate the momentum based on the mass and velocity of each ball. The explanation hinges on the relationship between mass, velocity, and momentum.
