Physics 100 Simulation Activity #2 Collision 3: Collisions Prediction Learning goals: . Explore momentum before and after collisions. . Explore what variables are conserved and under what conditions. For collisions 1-3, find the kinetic energy of each object before and after the collision. Show mathematically if your kinetic energy is conserved below Directions: with your work (KE=1/2mv?). Hint, KE is conserved if it is the same value Go to Phet and find collision lab or type in https://phet.colorado.edu/en/simulations/collision-lab before and after the collision. . Select "Explore ID" Click the green + to show Momenta Diagram . Click the box to show More Data . Have elasticity set to 100% Constant Sow INELASTIC Shift the elasticity bar (or type in new values). ANY NUMBER BUT 1.00 Collision 1: or 0.00 works. You may choose any mass value and any initial velocity . Predict what will each objects velocity and momentum be prior to and value. Pay close attention to the TOTAL momentum arrow. after collision (use formulas if needed!) Collision 4 Prediction Initial Values Before Collision: Actual Mass of object 1 initial v of 1 = initial p of 1 = Key: m=mass, v=velocity, p=momentum, =object 1, 2=object 2, initial (prior to collision), , final (post collision) Mass of object 2 initial v of 2 = initial p of 2 = . Let's see how you did, Hit the PLAY button, then record the data on the second line in the table. Elasticity = Total initial p= 3. Add your two initial momentums and your two final momentums Final Values After Collision: Sum of P.= Mass of object 1 final v of 1 = final p of 1 = Sum of pz Mass of object 2 final v of 2 = final p of 2 = Do two more trials of your own settings. Change the masses, initial velocities or both and record Did total momentum arrow change? Yeso Total final Collision 2 Prediction Collision 5 Pick a new non-zero, non-1.00 elasticity and run again Initial Values Before Collision: Mass of object 1 initial v of 1 = initial p of 1 = Mass of object 2 initial v of 2 = initial p of 2 = Elasticity = Total initial p= Final Values After Collision: Mass of object 1 final v of 1 = final p of 1 = Mass of object 2 final v of 2 = final p of 2 = Did total momentum arrow change? Yeso Total final Collision 6 Now set Elasticity to exactly 0.00 Initial Values Before Collision 1. Is Kinetic Energy conserved now? If so when Mass of object 1 initial v of 1 = initial p of 1 = Mass of object 2 initial v of 2 = initial p of 2 = 2. Did your total momentum ever change? If so when? Elasticity = Total initial p Final Values After Collision: Mass of object 1 final v of 1 = final p of 1 = 3. When fully inelastic what did the two objects do differently? Mass of object 2 final v of 2 = final p of 2 = Did total momentum arrow change? Yeso Total final For collisions 4-6, find the kinetic energy of each object before and after the collision. Show mathematically if your kinetic energy is conserved below with your work (KE=1/2mv?). Hint, KE is conserved if it is the same value before and after the collision
