The authors in this study examined the travel speed characteristics of passenger vehicles, trucks, and buses through different states with different speed limits policies, to arise and make certain of the effects of Differential speed limits (DSL) against Uniform speed limits (USL). The spot-speed data in this study was collected from the states of Indiana, Michigan, and Ohio. The data collected helped to examine the speed characteristics along the same freeways along several speed limit settings. The idea of DSL…

Speed is known as the ability to move the body or body parts quickly. In sports, this would be the maximum rate at which one covers a distance or performs a move. This component is needed in a plethora of health and fitness activities ranging from games, training etc. Speed is a vital aspect of fitness, especially when it comes to athletes such as sprinters. For example, a sprinter would require a great deal of speed in the 100m sprint…

Introduction When investigating the speed of sound in air, the measurement called ‘end correction’ is included to make the measurements more accurate. During IB physics HL lessons, our teacher did not show us how the end correction could be modelled as an experiment, or how the end correction of a pipe was found. What was fascinating was that the end correction was absolute, and given as 0.3d where ‘d’ was the diameter of the pipe. I was not comfortable with…

An investigation into how the velocity of a wave is affected by varying the depth of the water it travels through. A tray was filled to a certain depth with water and one end raised to 45mm above floor level. The tray was placed on a folder 45mm high for each experiment so the height from which that end of the tray is dropped remains the same throughout the series of experiments. The sliding out of the folder from under…

Ticker - Timer Practical Report Introduction This practical is investigating the motion of a trolley as it is placed at the top of an inclined ramp, and is released to roll down the ramp. With the aid of a ticker-timer, the average speed and acceleration can be determined, and using this data, the amount of force that the trolley has acting on it, can be calculated. The ticker-timer is utilised to determine the distance that the trolley travels in each…

The aim of this investigation is to determine the horizontal motion of a uniform particle when released down a ramp at varying speeds. The manipulation of speed will be achieved by positioning the projectile at different heights above a table, on a ramp. I believe that the horizontal component of the particle's travel will be proportional to its starting height, thus, if one is doubled so is the other. Equipment This experiment will require: Ball Bearing - projectile Ramp -…

The following investigation that I am going to embark on will involve the transfer of energy from one form to another. Usually when there is a transfer of energy from one component to another, these constituents are parts of machines or mechanisms, which are collectively classed as systems. In any one system there could be just one energy transfer or numerous transfers of energy. However, when we are dealing with systems, we must remember that there is no system that…

All objects, when no force is acting upon them, shall remain at the same steady speed, without accelerating or decelerating; so if an object is still, it shall not move and if it is moving then it shall continue moving so long as no force is acting upon them. This was explained by Newton's first law. However it must also be noted that the meaning of "no force" may also be understood as "all forces acting upon a certain object…

The aim of this experiment is to ascertain how the stopping distance of a toy car is affected by the steepness of the angle of the ramp. Diagram Safety Measures There aren't any safety aspects in this investigation. Apparatus During the experiment I used to the following equipment: Ramp 2x Metre Rulers Matchbox car Boss + Clamp Stand Prediction I predict that the steeper the ramp, the further the car will travel Fair Test To ensure that it was a…

The aim of this experiment is to determine whether or not energy is conserved when a ball bearing is rolled down a slope. Six weeks of preliminary work have been carried out ensuring that measurements can be taken quickly with the correct instruments needed for the measurement. Previous knowledge of energy conservation says that energy cannot be created or destroyed. What factors need to be controlled or varied in this experiment? In this experiment many factors need to be considered,…

I have decided to investigate how the height from which a squash ball is dropped affects the height of its bounce. When a ball is dropped, it accelerates until it collides with the surface - an impact. It then recoils, and some of the energy is reflected back upwards, causing it to bounce. I believe that as the height from which the ball is dropped changes, the speed of the ball at the moment of impact will also change. This…

Prediction of the relationship between the height used and the change horizontal distance travelled by the spherical mass. I believe that height is directly proportional to distance squared. This means that if the height is doubled the distance will quadruple. Explanation of the prediction in scientific terms. The formula to work out distance travelled is simply = average speed/total time, however there are many other formula used in working these two out. First the speed, or velocity must be obtained.…

I am going to see if changing the concentration of acid affects the speed at which it reacts with marble chips. Marble chips + Hydrochloric acid ( Carbon dioxide + Water + Calcium chloride CaCO3 + HCl ( CO2 + H2O + CaCl2 I will measure how much gas is given off by using a tally counter to count how many bubbles of gas are given off and measuring the volume of gas produced.

There are a number of performance requirements expected of a license plate recognition system. The system is expected to perform under many different conditions as discussed below: Speed The system is usually deployed in areas where the vehicles are moving at very high speeds. It is therefore important to design a system that will be able to capture vehicles as they move at very high speeds. A poorly designed system will produce blurry pictures of vehicles that are moving at…

After receiving a speeding ticket, I have come to the realization that speeding is not only dangerous but also costly in terms of time, money, and potential accidents. The consequences of speeding extend beyond just the individual driver, affecting other road users as well. In today's economic climate, wasting gas through speeding is not a wise decision, especially for someone who is currently unemployed like myself. The ticket I received has served as a wake-up call, prompting me to reassess…

Intro: Opening: Who here goes beyond the published speed limitation while driving? If a faster speed limitation was allowed, would you still go beyond the posted limit? Well, in Illinois, starting January first, 2014 you will legally be able to go just a little much faster on designated roads. I do not believe this is such an excellent change. Thesis: I think that raising the speed limitation will trigger more accidents and safety issues while increasing the consumption of fuel,…
