# Factors which affect stopping distance

Extracts from this document...

Introduction

Factors which affect stopping distance Introduction We are investigating the factors that affect the stopping distance of a wooden trolley. We have decided to change the mass of the trolley in this experiment. We will measure the distance that the vehicle takes to stop from when it hits the brake. Equipment Ramp Wooden trolley 4 1kg weights Piece of A4 paper folded to make a brake Light gate Data logger Meter stick Method We set up a ramp so that we could let the trolley roll down onto the brake and we didn't have to push it, which would be unreliable. ...read more.

Middle

We let the trolley roll down the ramp onto the brake and measured the stopping distance. We varied the mass by adding the weights one at a time and took three stopping distance measurements for each mass. I recorded the results in a table and put them into a graph. Fair Test To make this experiment a fair test, we will keep these factors the same: the surface of the ramp (so that the friction will be the same each time the trolley rolls down the ramp.) the gradient of the ramp (so that the trolley should go at about the same speed each time.) ...read more.

Conclusion

We will use the average distance from our three results to plot our graph. This means that our results will be more accurate. Prediction I predict that the trolley will have a longer stopping distance when it has a greater mass because the force of gravity pulls it down the ramp. When the mass is greater the force of gravity will be stronger so the break would have to use a greater force to stop the trolley which means that the stopping distance will be longer. stopping distance (cm) mass (g) 1 2 3 average 766 39 31 58 426.67 1766 86.5 75.5 85 823.33 2766 94.5 92.5 98 950 3766 74.5 100.45 97.5 921.67 4766 117.5 111.5 102 1103.33 ...read more.

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.

Kinetic energy is the energy of motion. An object, which has motion - whether it be vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational kinetic energy (the energy due to motion from one location to another).

Hypothesis There will be a difference in tensile strength between brown, blond, ginger and black hairs of similar thickness. Blonde hair (lighter coloured hairs) has more sulphur-sulphur covalent bonds than black hair (dark coloured hairs). Hair contains the protein keratin, which contains a large proportion of cysteine with S-S bonds.

The analysis of a ticker tape will reveal if the object is moving with constant velocity or accelerating. This is how we hope to record the acceleration of our trolley. To get the results from the ticker timer tape, you need to divide the tape into five dot strips, this is because each five dots is equal to 0.1 seconds.
