Experiment 1.06: Momentum March10, 2020 Objective: To explore the conservation of momentum after a body moving at constant speed collides with another stationary body.
Data: Time interval between sparks, Δt (sec).1 Mass of moving glider, m1(grams) 150.2 Mass of stationary glider, m2 (grams) 288 Before collision Spark number Time: t (sec) Location: s (cm) 1 0 0 2 .1 6 3 .2 13.9 4 .3 21.7 5 .4 29.4 6 .5 36.9 7 .6 44.4 8 .7 48.3 9 .8 51 10 .9 52.8 After collision Spark number Time: t (sec) Location: s (cm) 1 0 54.9 2 .1 56.7 3 .2 58.6 4 .3 60.4 5 .4 62.1 6 .5 63.7 7 .6 65.3 8 .7 66.8 9 .8 68.1 10 .9 69.5
Calculations: Speed of moving glider, u (m/s) .629 Initial momentum of system, p(initial) (N*s) .0944 Speed of gliders after collision, v (m/s) .1627 Final momentum of system, p(final) (N*s) .0712 Percent difference (momentum) 28% Speed of moving glider = .629 based on slope of graph Location vs. Time before Collision Initial momentum of system = m1* u = (150.2/ 1000) *.629 = .0944Speed of gliders after collision = .1627 based on slope of graph Location vs. Time after CollisionFinal momentum of system = (m1+ m2) *v = ((150.2/ 1000)+(288/1000))*.1627 = .0712
