Hybrid Car Lab
For our Hybrid Car Lab we had to construct a car that had to travel exactly 5 meters. We had to calculate how long it took to hit each meter and the velocity of the car when it was traveling. The car also had to carry a weight of 100 pennies which is about 250 grams because one penny is equal to 2.5 grams. 250 grams is equivalent to 8.81 ounces or a little over half a pound. Other groups used weights with certain amounts of 250 grams to imatate 100 pennies, but our group actually used a total of 100 pennies which were stored in half a plastic water bottle. The pennies were placed at the head of the model between the small front set of wheels.
Our car model had a triangular shape with the top point cut off into a smooth flat surface. The back of the model was also cut out into a triangle shap with the point cut off for the wheel and axle. The axle was connected by a round wood stick which was nailed in under the model with the wheel on the outside of it. We then attached a large mousetrap and glued two thin wood sticks on the side with two strings tied around the top. The string was then pulled back all the way to the wood stick with the big wheel attached to it and wrapped around the stick. To make the car go you would have to turn the big wheel till the string wrapped around it all the way and the mouse trap arms were pulled as far back as they could go. To see the model there is a photo if you scroll down the page.
For this lab we also had to present to the class, all the data and have multiple graphs on thermal, kenetic, total, and potential energy. We made a powerpoint to show all this data which you can access with the link below at the very bottom of the page.
