Investigation of the relationship between Force, Mass and Acceleration

Extracts from this document...

Introduction

Coursework: Investigation of the relationship between Force, Mass and Acceleration A1 A8 1. Firstly I will set up all the apparatus. The equipment that will be required to set up the experiment are: Rider with a weight holder on each side of it, light gates, string, pulley, stand, computer, carrier, air track, weights and air blower. The carrier is supported by something, whether it be a person or an object. (A8) The reason for this is to stop the rider from being pulled to the end of the air track under the force of the carrier. 2. The light gates will then be attached to a stand. They will be placed around 30cm apart. 3. The air track, with the air blower inserted inside of it, should be placed on a level desk (A8) to balance the force on the rider, thus stopping the rider having any horizontal force upon the rider. 4. The pulley will be attached to the end of the air track with the string resting on it. 5. Then the string will be attached to the carrier and the rider. ...read more.

This will continue until 1 Newton of weight is put on the carrier and the results recorded. All the individual forces will be recorded 3 times for accuracy.

Conclusion

As the error has remained constant throughout the experiment, it will not affect the gradient of the graph, therefore keeping the gradient constant. This was the most significant source of error. The reason why it occurred is because even though the surface of the air track was nearly frictionless, there was still some friction in the pulley, etc. At force 1.98, there is a rogue result. This would have probably been caused by the weight being caught too early or the weight swinging. D4 I believe this was one of the best ways of going about doing this experiment. It was a suitable method of reducing the friction. D5 I believe my conclusion to be reasonably reliable because some of the information to me was known beforehand, such as acceleration due to gravity. D7 To improve the experiment, I would place the air track on a higher surface to prevent the weights from being caught. This would have probably reduced a lot of error as when the carrier is caught, the string goes slack, slowing down the rider. It is too inefficient to not catch the carrier, because as soon as they hit any object, the weights on it go all over the place, making it very time consuming to replace them all. ...read more.

    Prediction I predict that the force will be proportional to the acceleration and so will also the mass will be proportional to the acceleration. However not in the same way, as the force increases the acceleration will increase but as the mass increases the acceleration will decrease.
