Stopping Distance
Planning
I am investigating how the stopping distance of a car is related to the speed that it is going and how
much force is used to stop a car going at a certain speed and for a certain distance.
For my experiment I propose to test the distances need for a car travelling at certain speeds,
due to Kinetic energy being converted into other types of energy. I could set up a simple apparatus that
will be sufficient to take accurate readings from. I will drop a toy car from a ramp that is a set height,
then measure the speed at the bottom and measure the distance the car travels. From this I can work
out the original gravitational potential energy and the kinetic energy and therefore the energy converted
to other types of energy. I predict that the gravitational energy will not equal the kinetic energy because
some will be lost to sound, heat and kinetic energy in other directions from the forward direction
desired. I will have a ramp help up, a ruler going along the side to measure the distance the car travels.
On the car after every three runs I will add 100grams. I propose to do the experiment 3 times for each
height of block so that I can work out the average, by doing this I will make the experiment more
