In this experiment, we tried to establish the F=MA equation. We did this by creating a system which involved a Car, being pulled by a pulley which was attached to some masses (Weight, which in this experiment acts as force, Weight is mass being accelerated by gravity.) In the first experiment we moved the Weights from the Weight, to the Car (Turning it into Mass). This is graph One, which is the upper of the two. And the results are to the left of it. The second experiment was where we only added to the Mass of the car. Activities: Plot the gradient, as the Acceleration and Mass have been listed, put these values into F=MA and see if the Gradient is equal to F. If so why so? If not, why not?

Lightgates height vs velocity
Results for an experiment where the height of a ramp, down which a car is rolled, is varied. The velocity of the car is calculated using a lightgate.
The mass of the car was 53.7g
