To find out the effect on speed of a trolley going down a slope

Extracts from this document...


Aim      To find out the effect on speed of a trolley    

         going down a slope

Safety   Use a barrier – so the trolley does not roll  


         Make sure the slope is secure – so it doesn’t    

         topple over

         Cello tape the weights down – so they don’t fall  


         Goggles are not needed for this experiment


Apparatus  Trolley, slope, books, weights, cello tape,  

           stopwatch and a metre ruler

Plan       I plan to find a surface suitable for the

           experiment and build my slope. At first I will

           use 2 books and gradually work my way up to 20

           books timing and measuring the distance it

           travels. I will then find the size slope  

           in which the trolley travelled the furthest

I could make the experiment and results more accurate with more complex apparatus, time it more accurately, use heavier weights (I only used light weights and they did not really make a difference). To extend this work, we could conduct Galileo type experiments, but take them a step further. Perhaps, if we had the access to the right equipment, we could drop weights from different heights in a vacuum (i.e. no air resistance), calculate the speed using light gates and see if it produces theoretically perfect results. We could also try eliminating any other opposing forces, such as friction, by polishing surfaces etc. and noticing if this changes the results.

    As these 2 factors will effect the acceleration; I will have to add an equation to remove the results of friction; the equation I will need to add is a?=gxsin? -?. We will not be calculating the results of friction in this experiment; but I have predicted the results if we did in the following graphs: 1.

  2. Factors affecting the speed of a trolley Travelling down a ramp.

    A tripling of the height will lead to a tripling of potential energy. Potential energy is energy which is stored in the system, and this energy is only thought of when the system is stationery but when the system is in motion, kinetic energy comes into play.

    For there to be acceleration there must be a resultant force or the forces must be unbalanced. By the cart accelerating down a slight slope to counterbalance the effects of resistive forces. As the graph shows that the speed does stay constant, so mass can't affect the speed of the

    Finally human error may force the distance travelled and starting speed to vary slightly, as the trolley has to be release by hand, and there for human error may cause anomalies via the start. The only way I can keep this as fair as possible is by releasing the trolleys

    I conducted preliminary experiments to found out which variables were the most practical to focus on. The basic aim is to narrow my search down to one or possibly two variables and then find the most power-efficient value for each variable.

    This has lead to what is called helical scanning. Helical Scanning: According to Synergy Magazine, which is the largest radiography title in the UK and arguably the most reliable, the use of slip rings has improved the CT vastly. It has eliminated the need for high tension cables, allowing continuous gantry rotation, as well as making helical scanning possible (explained in detail below).
