Investigating The Stopping Distance Of A Toy Car

Extracts from this document...


Investigating The Stopping Distance Of A Toy Car PLANNING: During the course of this investigation i will aim to find how one specific factor effects the stopping distance of a toy car down a ramp. The factors which effect stopping distance are; Tyres, Brakes, Road surface, Speed of car, the Aerodynamics etc. The toy car will model a real car with frictional forces between the bench top and the wheels acting as brakes. I will choose to investigate the effect of speed because it is the most easily varied. To change the speed of the car i can alter the height at which the car falls from. This is done by adding or subtracting blocks which make up the height of the ramp. Speed will be measured by using a light gate, and the stopping distance of the car will be measured using a ruler. ...read more.


this will cause the car to crash into the bench rather than rolling down the ramp and then along the bench top. Speed will be measured using the formula, speed = distance travelled. Time taken Predictions: The higher the speed of the car, the higher the stopping distance. This is because at higher speed there will be higher kinetic energy belonging to the car. Therefore it will take longer for frictional forces acting on the car to put it to rest. I can show this using formulae: Loss in kinetic energy = work done by frictional forces 2 1/2 MV = F x d By rearranging this 1/2 Mv formula i can get: D= F x 2 = D= M 2F So to find the theoretical stopping distance of the car I can use the above formula. If we assume that everything remains constant i.e the frictional forces acting upon the car, the stopping distance must be proportional to the speed of the car. ...read more.


Braking distance has been multiplied by 4. If the speed trebles from 20mph to 60mph the braking distance is multiplied by 9. Implementing The experiment was performed, whereby the car was dropped from varied heights, and the times which the car took to go through the light gate were noted. The stopping distance was also recorded, and each measurement was performed three times so that an average could be made to produce more thorough results.

    different point than when another person would tell them to, hence having an effect on the results. Light-gate Connect a light-gate device to a computer, and place it where ever you want to position it in order to calculate the ball's speed, works by using a laser beam as a light sensor detecting how fast the ball is going.

    > The desktop where my investigation will be taking place should be straight therefore it won't affect the results of the investigation as a bent desktop may increase the speed of the car and thus would eventually lead to an increase in stopping distance.

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

    * Gravity - This factor is hard to change unless you go to a different planet, but it is still an independent variable because it is used in the equations for potential energy, acceleration and weight. Therefore, any change in gravity will affect the values for these equations.

  1. Factors Affecting the Speed of a Car after Freewheeling down a Slope

    This would show why my experimental results were not exactly the same as seen in the theoretical graph, in which these factors were ignored. It was interesting to note that the speed of the trolley in my experiment at 0.30m height and 0.45m height of the ramp was exactly the same.

  2. Investigating the relationship between the speed of a model car and its stopping distance.

    several areas where friction occurs: between the car and working surface is the most obvious, but there will also be friction between the axis and chassis of the car. This friction will slow the car down, as the Kinetic energy* in the vehicle converts to heat and sound energy that dissipates into the car and surrounding atmosphere.

  1. Approximate Stopping Distances

    increases the braking distance increases even further, when the speed is doubled the braking distance doesn't double, it quadruples which means the overall stopping distance is not proportionate to the speed of the vehicle. Thinking distance is the distance the vehicle travels after the driver has seen or heard something

  2. Trolley Speed

    Before we let go off the trolley, I held the ramp so that it would not tilt and therefore it would not interfere with the speed of the trolley as it travelled down the ramp. These above factors will also give me more accurate and reliable results.
