Part (2): m1m2 1) KEEP: Elasticity at 100% 3 2 2) Select: m1 = Akg and m2 = 3kg 3) Position 1 (-1.00m) and position 2 (0.00m) iela 4) Select: V1i=1.00m/s and v2i=0.5m/s
Do they all have the same K/K? explain. Questions: 1) What is the difference between elastic and inelastic collisions? 2) Discuss the difference you saw when (mama) and when (m: 7 m). 3) Move the elasticity slide to 0% (completely inelastic). Run a simulation or two and see what changes and what does not. Describe the motion after collision. Is momentum still conserved? Is K? Write a comprehensive summary of what you learned in this lab. Make sure your summary is related to the lab's objectives.
Conservation of Linear Momentum Objectives Determine the velocity between two objects after a collision and the momentum of each ball before and after the collision Collision types and kinetic energy evaluation . . https://phet colorado.edu/sims/html/collision-lab/latest/collision.lab en html If you are in the correct place, your screen should look like what you see below. Collision Lab END Ecotea Intro PHET: Theory: Newton's second law is written with the formula Forma = m(Av/At) = A(mv)/At = Ap/At where Fre is the net external force acting on the system during the collision and (p) is the net momentum of the system. This momentum is given to an object by its mass (m) multiplied by its velocity (v); p=mu, which is a vector quantity. If Fret = 0, then (Ap / dt) = 0, which means (P) = constant. Therefore, when two objects collide on a horizontal surface devoid of friction, the total force acting on the system during the collision is equal to zero which means that (p) = (P.) where (p) is the vector sum of the momenta of the two objects before collision and (p) is vector sum of the momenta of the two objects after collision. And for the calculation of speed: m V1 + m2 Vzi = m; Var + m2 V2f
