Data Interpretation and Analysis

Activity 1: Planning and Carrying Out the Investigation A group of physics students are conducting a study using a Hot WheelsTM car. Their arrangement of equipment is shown in Figure 1. The car is placed on the track at position (A) and released from rest. The car rolls down the track to ground level and passes through a photogate timer. The photogate timer measures the time for the car to pass through it, allowing the students to calculate the speed. Immediately after passing through the timer, the car hits a small box (B). The car lodges in the box and slides across the floor to a final stopping position (C). The students measure the initial height of the car (hA) and the photogate time (t) and calculate the speed (vB). The students also place a meter stick along the floor so that they can measure the distance that the box and car skid before stopping (dBC). Students plan to conduct five trials. Their data collection plan is shown in Table 1.
