Toy Car Physics Essay

778 Words4 Pages

Discussion:

An experiment was conducted to determine the effect of multiple forces on a toy car. According to the hypothesis the less friction upon the toy car, the stronger the driving force, also referred to as as momentum. If the hypothesis is true, the toy car should have less friction, more momentum would be created, resulting in it going forward. There were multiple forces acted on the toy car. Three of those forces were gravity, driving force and friction. Gravity was one of the fundamental forces in this experiment as it generated the momentum to allowed the car accelerate. Momentum was very important as it was the only reason the car accelerated. As force is generated by the equation of force = mass x acceleration. Friction was the …show more content…

The difference between the smooth surface and grassy surface is 199.4cm. Therefore the smoothest surface has less friction. An explanation for this is, the momentum generated by gravity was the strongest as there was the weakest friction because there was no crevices in the surface. In addition to this, the science lab surface was completely flat and the surface was unable to hook onto the car. (Q2)

According to the results obtained, shown in the table, the grassy surface was the surface the toy car went the shortest distance of 36.8 cm. An explanation for this, the friction generated by the grassy surface overthrew the momentum. The grassy floor was very uneven and there was multiple crevices to stop the toy car.(Q3)

The motion of the toy car was affected heavily by gravity, momentum and friction. Gravity affected the motion of the toy car heavily as without it the toy car wouldn’t of stayed the surface and the toy car wouldn’t of been able to generate momentum to allow the car to accelerate. Momentum was one of the main reasons there is continued to move as it was shown in the results, the science floor surface, the smoothest surface, the toy car went the furthest. The results confirm the hypothesis and confirm momentum is very important. Friction made the toy car to decelerate. The hypothesis was correct as the toy car had the most friction and went the least furthest on the grassy surface.

    The hypothesis was that the more mass a car has, the faster it will go. This hypothesis was partially rejected though. One reason that the car got slower on the last race could be because of wear and tear. It took awhile for the track to work properly. The end has a wall,and if the car hit it at the high speeds it was going, it may damage the car.

    Data Analysis Does the type of ball affect how far it rolls when rolled down a ramp? The hypothesis for this experiment was “If the different types of balls are rolled down a ramp, then the soccer ball will roll the farthest.” The independent variable, the variable that was intentionally changed, were the types of balls. The distance each ball rolled is the dependent variable. The experimental group includes the soccer ball, the basketball, the tennis ball, the golf ball, the marble, the baseball, and the ping pong ball.
