Braking Investigation

Conclusion:- From the results I have found that as the kinetic energy goes up the stopping distance goes up. This is because there is more energy in the movement of the bike, which means that it needs more energy to stop the bike.

I also found that as the heavier the rider the velocity became lower and even though the velocity was lower the stopping distance was bigger as there was more force needed by the brakes to stop the rider. If the rider was lighter the velocity went up to a much higher velocity than the heavier rider. But the stopping distance was in some cases lower than the heavier riders. This maybe because even though the rider is lighter and can go faster

The prediction that the braking distance of a car or bicycle depends upon the kinetic energy it has before the brakes are applied is true. This is because the stopping distance can vary due to the velocity and kinetic energy. If the velocity is fast then the stopping distance will be further, this is because there will be more kinetic energy the more force will need to be exerted into the brakes to stop. We can work out the work done by doing an easy sum – force x distance. The greater the kinetic energy the greater the force of distance must be. The main trend that can be found is the one that tells you that if you double the velocity the KE gets four times bigger - v² = KE x 4 >.

From the range bars I can see that most of the results were accurate, apart from one anomalous result (labelled on diagram). The line on the range bars is nicely curved showing a gradual drop in speed.

Another way of conducting the experiment would be to use a car, as you could set up velocity meters in it, and the readings could be much more accurate for the time.

    * At higher temperatures the ball does in fact stop bouncing as high due to excessive heat melting the atoms of the ball (as more and more energy is given to them to break their bonds), resulting in a curve on the graph proving this part of my prediction to be correct.

  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.
