Motion of a mousetrap car Lesson 19 Motion of a mousetrap car

Getting Started Build your mousetrap car – diagram on p. 190-191 It takes energy to run the mousetrap car. How can you put energy into your car?

Inquiry 19.1 Observing the Motion of the Mousetrap Car Set the car on the table or floor and attach a spring scale to the mousetrap bar. Holding the car firmly, slowly pull the bar back with the spring scale. Observe the force on the spring scale as you pull the bar. Record what happens to the force as you keep pulling the bar. Slowly release the bar so that it returns to its resting position; remove the spring scale.

Hold the car so that it does not touch the floor Hold the car so that it does not touch the floor. Set the mousetrap spring by turning the wheels of the car so that the nylon line winds around the axle and pulls the mousetrap bar all the way back. Let go of the wheels while you are still holding the car off the floor. Do this several times, describe what happens.

Data What do you think the motion of the car would be if you set the mousetrap and released it with the car on the floor? Reset the mousetrap, set the car on the floor and release it. Describe what happens. 2. Write a paragraph describing the motions of the mousetrap car after the trap was set and the car was released. Describe what forces you think are producing the motions.

Inquiry 19.2 Measuring the Speed of the Mousetrap Car Discuss the following: Is the speed of the car constant as it moves across the floor? How could you calculate the average speed of your car? How could you design an experiment to measure the speed of the mousetrap car as it travels along the floor?

Data Time and Distance of Mousetrap Car Distance Interval Position (m) Trial 1 (s) Trial 2 (s) Trial 3 (s) Average Avg. Speed (m/s) 1 0.0-0.4 2 o.4-o.8 3 o.8-1.2 4 1.2-1.6 5 1.6-2.0

Data Questions Summarize what you found out about the motion of the car. Give evidence from your data for your conclusions. Explain the changes in the mousetrap car’s speed in terms of the forces acting on the car. When you set the mousetrap, do you do work on it? If so, explain.

Write a paragraph describing the energy changes that took place when you set the trap and released the bar. How does the motion of the mousetrap car compare with the motion of the fan car? Identify similarities and differences.
