IN THIS FIRST PART OF THE LAB, WE WANT YOU TO OBSERVE WHAT HAPPENS VlSUALLY WITHOUT TAKlNG MEASUREMENTS; YC ESTiMATE VELOCITIES {NO NEED TO BE PREClSEJ)' First describe in words two different collisions: 1} elastic and 2) inelastic. You can choose the initial velocity of each object and y the mass of each IOLAB by adding masses using the mass set to each lOLab (you may need to use tape to make sure the masses 1. Draw the motion diagrams (on next page) with your coordinate system labeled and the velocity versus time graph for ea the collision. You can and should perform the collision with your IDLab to see what happens but do not take data yetl _ . Inadequate ' Adequate . Good Motion Diagram Diagram does not show Diagram has correct The diagram contains no proper motion: either spacing of the dots but is errors and it clearly lengths of velocity arrow is missing velocity arrow. describes the motion of incorrect or missing and or the object. Dots and spacing of dots are velocity arrows are
