Introduction

Physics Course Work: Investigating Stopping Distances of a Car

Plan

I am going to try and find out some information about how the stopping distance of a car, caused by the speed of the car before it begins to stop. To do this I am going to roll a marble down a wooden ramp onto some carpet from different heights and making the marble hit the carpet at different angles.

I came to the conclusion that using a marble is the best

As you can see the marble had the least range between the rolls so it was the most reliable test. I decided to do the experiment on the carpet because I tried all three balls on the bare floor, the carpet, the yard and

Conclusion

Now I have chosen which ball and surface I am going to use for my investigation I am going to carry it out. To do this I am going to roll a marble down my wooden ramp from different heights to find out how the speed of a car effects the stopping distance by seeing how much kinetic energy the ball loses once it has converted its gravitational potential energy.

The result must be between 2.8 and 3.6N/mm at 23oC. In other words, the force required to compress the ball by 16mm (i.e. to just over half its original diameter) must be between 44.8 and 57.6 Newtons. The calculation of seam strength is even more complicated.

2. Approximate Stopping Distances

For example it is the time required to detect that a pedestrian is walking across the road directly ahead and to decide to apply the brakes. Movement Time: Once a response is selected the driver must perform the required muscle movement, for example the time it takes to lift the foot off the accelerator pedal and press the brake pedal.
