Caden McDonald 2/26/20 Motion with Constant Acceleration Introduction : In this virtual lab, I used an online simulation to record the velocity and position of a cart that is being propelled by a an on top as it accelerates across a surface of no friction. I used multiple graphs to record my data. Purpose : Observe how an object’s position and velocity change while it is moving with a constant acceleration at different speed with this virtual simulation. Question : How does an object’s position and velocity change as the object accelerates? Hypothesis : The more force that the fan creates, the more the cart will be propelled forward. Materials : - One computer with access to virtual lab Materials within Virtual Lab : • Fan with three speeds - A Low speed - A Medium speed - And a High speed • Cart with the fan on it to propel it forward • Odometer • A surface with no friction • Track which ends at 500 meters • A computerized Timer Procedure : 1. Open the simulated virtual lab. 2. Select a fan speed of: “Low”, and “No Friction” for the type of surface. 3. Open the “Data” tab and select the buttons “Speed and Line graph.” 4. Click the “Play” button. 5. Record data from the “Speed” data table into Table 1 in the column of "fan speed: Low”. 6. Record the total distance to the finish line, and the total elapsed time in Table 2.
