The table below shows the results including average times and calculations of acceleration:
Mass Force (N) Distance Speed (m/s) Average Time (S) Acceleration (m/s theoretically) Acceleration (m/s experiment)
Firstly, the speed was calculated by dividing the distance by time. The common formula of speed, distance and time was used to work these results out. The distance is constant at 1metre divided by the average time(measured in seconds) equals to the speed written in the units of metres per second. From working out the speed the acceleration can also be worked out. The acceleration of an object is the rate at which it's velocity changes. It is the measure of how quickly an object is speeding. With the results of this experiment the acceleration can be calculated by dividing the speed with average time. This should result to acceleration measured in m/s?. Graph 3 shows as the force of the object increases the acceleration also increases depending on the mass of the object. As the mass becomes heavier the acceleration decreases.
Speed (m/s) = Distance (m) Acceleration (m/s?) = Change in speed (m/s)
Time taken (s) Time taken (s)
Example: Velocity = distance divided time taken
Velocity = 1 metre divided 3,16 seconds
Acc = change in speed divided time taken
Acc = (0.32 metres per sec – 0 miles per sec) divided 3.16 sec
= 0.01 metres per second? (m/s?)
Force (Newton's) = mass (kilograms) X Acceleration (metres per second?)
Example: Acceleration = force divided mass (F=MA)
Acceleration = 0.1 Newtons divided 1 kilogram
