I a blue ball + a red ball moving toward each other bounce off each other after colliding timepoint 1 timepoint 2 timepoint 3 . Energy is conserved ( perfectly elastic collision) : El = Ez= E3 . linear momentum is conserved be no external forces in & direction : P. = P. = P. blue ball moves toward stationary green ball. After collision, green ball moves and blue ball becomes stationary. timepoint 1 timepoint 2 timepoint 3 VI= y . energy is conserved; elastic collision : E. = Ez = Es { total energy? . linear momentum is conserved ( same as above ): P.= P, = P. 3) blue ball moves towards stationary orange ball. After collision, they stick together + move together. timepoint 1 timepoint 2 timepoint 3 VI = y move w/ 1 velocity . Energy is NOT conserved, because inelastic couision . linear momentum is conserved ( same as above ) : P, = P2 = Ps4 blue ball hits stationary pink ball. After collision, blue ball moves with 50% reduced speed in direction: - 9 with respect to x-axis, and orange ball moves at same speed in direction: +0 with respect to X-axis . timepoint 1 timepoint 2 timepoint 3 7/2 X >x . energy is conserved, because elastic collision : E, = Ez = E3 . linear momentum is conserved in * and y: Prix = P2x = P3 and Puy = Pzy = Ps,y 5 blue ball is thrown at a red apple hanging from a tree . After collision , blue ball moves at same velocity as before and red apple now has velocity and drops to the ground. timepoint 1 timepoint 2 timepoint 3 X X X energy is conserved ; however, if a sound OR heat was produced during couision, energy would NOT be conserved. . Linear momentum is NOT conserved in * OR y direction ?? "because gravitya mass in space randomly explodes into 3 equal parts, that each move w/ 3 V. timepoint 1 timepoint 2 time point 3 Vi X energy is conserved : 51 = Ex = E3 V 2 . linear momentum is conserved : P. = P2 = Pg 1 a mass is space has angular momentum, s, around a pink planet and angular momentum, w, around its own axis. It randomly explodes into 2 pieces. The green piece moves with the same s around pink planet and direction but different magnitude of was Original mass. The orange piece moves with same magnitude of w as original mass, by in a different direction . timepoint 1 timepoint 2 time point 3 V. . energy is conserved, because no non- conservative forces present : E, = E 2 = E3 . linear momentum is NOT conserved . . angular momentum is NOT conserved.8 a blue ball hits a hanging stick and sticks. Both objects move together at angular speed, w', around y-axis . time point 1 timepoint 2 timepoint 3 > x . energy is NOT conserved because inelastic collision ( sticking) . momentum is NOT conserved because linear becomes angular ( timepoint 1) ( timepoint 3)
