![]() Students use the data to create graphs and analyze the reliability of their experiment. We used a simple ramp made out of Hot Wheels track propped up on blocks for this experiment. However, we used the ramp in this example in the opposite wayto move objects downwards When a ramp is placed at different heights, the time it takes for an object to move down the ramp. Using an inclined plane reduces the amount of work (force) needed to move an object upwards. In this case, the force stopping the car is friction between the wheels and the floor. A ramp is a type of simple machine called an inclined plane. ![]() Once the three trials are complete, head back to the classroom and use the data collected to analyze the speed of the vehicle between various points and overall speed. So the heavier car will roll farther because it has more momentum and it takes more force to stop it. As the car passes each point, the students should record the time in their data charts. Students will then use the data to create graphs and analyze experiment reliability. ![]() Using a 5 meter "race track," mark off 1, 2, 3, 4, and 5 meter positions. Summary Students will investigate the motion of toy cars and collect data to analyze the speed of the vehicle between various points (positions) and overall speed. To perform the tests, create a "race track" and position five students armed with stop watches at various points along the track. Students will then use the data to create graphs and analyze experiment reliability.Īny type of toy car may be used including, Matchbox Hot Wheels, wind-up, or remote control vehicles. Students will investigate the motion of toy cars and collect data to analyze the speed of the vehicle between various points (positions) and overall speed. ![]()
