Motion and Force Practice

Motion and Force Practice
Toy Car Race
Ms. Williams’ science class uses a toy car race to study and collect data about forces and motion. The
racetrack shown has a 12-meter ramp and a 6-meter level section to the finish line. Two cars compete at a
time.
The data table and graph below show the time and total distance traveled for car 1 and car 2 during the
race.
1. Calculate the speed at each location.

2. Using the distance and time graph, plot the data for both car 1 and car 2.
3. What is the shape of the line as the cars are going down the ramp?
4. What is the shape of the line when the cars reach the level location?
5. What does the shape of the curve in the level location and your answer from question 4 indicate is
missing on this section of track?
6. Using the shape of the graph for car 1, draw the free body diagram at each of the following locations:
Start
Ramp
Level
7. Would the free-body diagram for car 2 be different from car 1? Why or why not?
