ACTIVITY 2: ELASTIC COLLISION - PARTI You will study an elastic collision between two gliders. One of the colliding gliders will be at rest before the collision. To determine whether linear momentum was conserved in the collision, you will use the mass and speed measurements of the gliders to calculate their momenta both before and after their collision MATERIALS • Air track • Two gliders Timer • Air blower Two photogates Elastic-collision accessories Leveling instrument • Set of slotted objects • Meter stick • Beam balance EXPERIMENTAL SETUP Except for the replacement of the inelastic accessories by the accessories for an elastic collision, the setup for this activity is the same as the setup for ACTIVITY L. MEASUREMENTS 1. Add 50 g objects to each side of the glider at rest glider 2). Measure the mass of each glider and record your measurements as m, (mass of glider 1) and m, (mass of glider 2) in Table 7.2. 2. Launch glider 1 from the end of the air track at which photogate +1 is located so that it will collide with the glider that is at rest. Record the velocities of the gliders in Table 7.2 on the LAB REPORT, using the same sign convention you used in ACTIVITY 1. 3. Repeat this procedure two more times. Complete Table 7.2 and answer QUESTION 4. ACTIVITY 3: ELASTIC COLLISION - PART II Note: Use the space provided on the laboratory report sheet to organize your data and calculations for this activity Use the same equipment you used in ACTIVITY 2 to setup an experiment in which the two gliders collide when they are moving toward each other. Be sure to locate the photogates along the track at locations where the initial and final speeds of the gliders can be measured. Do several trial collisions, but make your measurements for only one collision Record your results in Table 7.3 on the LAB REPORT. Answer QUESTION 5.
