The title of my investigation is how I can change the acceleration of a trolley?
... must be applied to the trolley so that the acceleration of the trolley can be measured. Using a Newton meter I will pull the trolley with a constant force. The problem will be that it is difficult to provide constant ...

This experiment is designed to approximate ì, the coefficient of friction, for two surfaces. We used a piece of rubber on the bottom of a wooden block on a wooden table.
... This will affect the results as forces will not be constant during the experiment, and therefore produce irregular acceleration. Light, smooth pulley This will affect the results in the same way as above. We attempted to use the smoothest pulley available, but ...

To calculate the acceleration due to gravity by dropping a ball from a certain distance and recording the time
... of the plate - a circuit was made between the release mechanism, the trip plate and the electronic timer. it was configured to start counting as soon as the ball is released and to stop counting when it touched the plate - ...

To determine the acceleration of gravity in a free fall experiment.
... timer represents how long it took for the ball to reach the trapdoor. * The experiment is repeated several times at different heights, with 2 readings for each height. * Results are put into a table showing the distance, times, an average ...

To find out the effect on speed of a trolley going down a slope
... I predict that the trolley will travel further on a steeper slope and with the most weights on as there is more potential energy on a high slope and weights on than a flat slope. The more ...

To find out what effects the acceleration of a small trolley with a weight of 1kg.
... this: Issac Newton said in his 2nd law : 'The rate of change of momentum of a body is directly proportional to the external force acting on the body and takes place in the direction of the force.' F rate of change ...

To find out what happens to the distance travelled by two standard tubes of different circumferences down a wooden ramp propped up by books, when I alter the height of the ramp and make the release height higher.
... gravitational pull acting upon the tube. Obviously, the more potential energy the trolley has got, the faster it will move down the ramp. So, theoretically, the only factors that can affect this experiment are the height and the mass and ...

To get any object to move in a circle you have to apply a force to it
... bung around above your head whilst holding the tube until the forces are balanced. If you spin it too slowly the weight drops down, if you go too fast it rises up. You need to adjust the speed of spinning ...

To investigate how the depth of sand in a cylindrical vessel affects the amount of tilt to which the vessel can tilt to whilst remaining stable.
... can no longer fall back on its base when tilted so far. Instability is caused when the centre of gravity of an object is no longer over the pivot through which the object is being tilted: The object on the ...

To investigate the affect of changing the force applied to a cantilever on its deflection.
... of ruler (the greater the length is the greater the deflection) * Distance from clamped end the force is applied to ruler (the greater the deflection will be because the turning effect is greater * Method of measuring the deflection (use the ...

To Investigate the Factors which Determine the stopping Distance of Rollers down a Ramp.
... A fixed interval (3,6,9ect....) To find out if my predictions were correct, I conducted an experiment. It was set up as follows; The Experiment Aim - to investigate the factors, which determine the stopping distance of rollers down a ramp Apparatus- 1. 3 ...

To prove that a falling body has a constant force of gravity on it, no matter what the distance or time taken for the object to fall
... through gate A and the final velocity through gate B. The readings that the computer shows will have only a 1% error. To make sure that the values of "g" I calculate does not just apply to that one situation ...
