How Force Effects Acceleration

Planning

In this investigation I will investigate the relationship between force, mass and acceleration. Force is proportional to acceleration because if I push a trolley harder the acceleration is higher. If I put something in the trolley then the acceleration would lower so the mass is inversely proportional to the acceleration.

Force  Acceleration

Force  Mass-1

The formula could be rewritten as:

Force = Mass x Acceleration

(N)   =  (Kg)  x      (m/s2)

This investigation will attempt to prove this formula in a practical. To calculate the force I will use gravity acting on weights as shown in my diagram below. 100 g will give a force of 0.98 N. Mass can be measured on a scale. Acceleration will be measured using a light gate as shown below. The formula for acceleration is:

Acceleration = Change in speed / time

(m/s2)      =           (m/s2)        /  (s)

The formula for speed is:

Average speed = Distance / time

Conclusion

Evaluation

The procedure I used worked and gave good constant results. This is clear when you look at the results and notice how close the results are to the line of best fit. It would be more accurate if I had repeated the test more times. The procedure was suitable however inaccuracies occurred because not only did the trolley accelerate but so did the weight. To improve this experiment I would then have to only have one thing accelerating such as a falling object. There is also friction which could be lowered by using thinner wheels and a more streamline trolley. A falling object would also get rid of friction between the slope and the trolley and air resistance could be calculated out of the experiment. The evidence is constant and is so sufficient enough to support the conclusion. It would be more accurate if I had repeated the test more times. Additional data could be collected to further my investigation by changing the weight of the trolley or changing the force.

The force of friction is at its maximum between two objects when they are at rest. The angle of friction- the angle to which a surface must be raised for objects placed on the surface to begin to steadily slide, thus the force of friction is removed.

Fair Testing It is important to keep the factors of this experiment fair and by doing this I will have only one independent variable element which will be 'mass of trolley'.

o Inaccurate reading of the height. Even though a metre rule was used to ensure the height could be measured to the nearest centimetre, when the ball was bounced, it bounced back very fast and reading the height at which it bounced back proved to be difficult.

2. ## An investigation into factors that effect the braking distance of a trolley

Obviously, factors such as gravity and air resistance cannot be altered, so there is no point worrying about it. To produce a fair test the many possible variables must be controlled and kept constant so they do not have any effect on results obtained.
