Physics Lab Report Lab 3: Energy and Momentum Group and name Abstract: In our experiment, we were trying to find the energy loss due to semi elastic collision and friction. Also we found the efficiency of the collision using certain equations. We found out that the loss of energy due to semi elastic collision is a lot more than the loss of friction. We had many external errors with measuring because of our inaccurate source of measuring system. The materials we used were 6 steel ball bearings, a U-track, meter stick, and triple beam balance. Objective: The objective of this Energy and Momentum lab is to find out the loss of kinetic energy due to the friction. Also we are trying to find the loss in kinetic energy through and semi elastic collision. So we are undergoing this experiment to find out what we want and then if our losses are consistent then our systematic error can be removed to analyze our data. Now we can leave out un-useful energy so we would be efficient. Experimental Design: In this experiment we used many supplies such as, a u track, 6 steel ball bearings with different mass, a meter, and triple beam balance scale. In our experiment we first massed our marble to find out how much mass of each marble would be. We had two of the same sized marble though the mass will be varied. We used the u-shaped track with 5.0cm vertical increments from the base U to measure how high our marble will go up. Then we got a ¾ ball bearing and dropped it from increments of 10cm to 40cm. We repeated these steps for the other marbles with different ball bearing. We had members of the team to approximate the height of the marble going up after the drop. We used the meter stick to see how high starting from the base of the U. We did not have an exact number but we had an estimate. We had a releaser who drops the ball at the certain increment. It is important that
