Colorado phet 30% elasticity

Click "Reset All" In the box on the right side of the screen, select the following settings: velocity vectors ON, reflecting borders OFF, and momenta diagram ON. Choose any masses, velocities, and elasticity. Trial 4: Elasticity 30 % Before: Mass of green ball: Mass of red ball: Velocity of green ball: Velocity of red ball: Momentum of green ball: Momentum of red ball: Momentum of System Before Collision (Pred + Pgreen) = Click play, and then fill in the information below for After: Mass of green ball: Mass of red ball: Velocity of green ball: Velocity of red ball: Momentum of green ball: Momentum of red ball: Momentum of System After Collision (Pred + Pgreen) 14. What happens to the momentum of the red ball after the collision? a. Increases, but stays in the same direction b. Increases, and changes direction c. Decreases, but stays in the same direction Decreases, and changes direction 15. What happens to the momentum of the green ball after the collision? a. Increases, but stays in the same direction b. Increases, and changes direction c. Decreases, but stays in the same direction d. Decreases, and changes direction 16. What happens to the total momentum of balls after the collision? a. Increases b. Decreases c. Stays the same
