Speed Affects Braking Distance Of A Car Travelling Down A Ramp At Different Heights

#1. I believe that decreasing the diameter of the front wheels will significantly impact on the distance that the mousetrap car will travel this

In this lab, we applied the concepts of velocity,force, acceleration, time, and distance in order to calculate which trial had a higher velocity. We also learned the relationship between each of the factors and how altering one plays a role in the other factors. For example, if we were to apply more force the velocity of the cart would increase, as well as the amount of time it took for the cart to go down the

The purpose of this laboratory experiment is to construct a mousetrap vehicle. The vehicle needed to go travel five meters. My partner and I build a mousetrap car that obtain a two-axle vehicle with four CDs making the produce optimum acceleration and travel.

#1. We added an extended lever arm to increase the distance of the car. We put the lever arm on, because the bigger the arm, the less force required. The larger the lever arm , the less force is required to pull the string. On our car we originally had no lever arm, when we put the arm on, the cars distance changed due to the less force required to pull the string and that means

Using Vernier, we clicked collect while releasing the cart after motion detector starts to click. This was done moving the hand quickly out the path. Using logger pro, indicated which portion was to be used by dragging across the graph to indicate the starting and ending times. Then the linear button was clicked to perform the linear regression of the selected data. The Linear Button was used to determine the slope of the velocity vs. time graph, only using the portion of the data for times when the cart was freely rolling. We found the acceleration of the cart from the fitted line. Record the value in the data table. These steps where repeated 5 mores times. Measured the length of the incline, x which is the distance between the two points of the ramp. Measure the height, h, the height of the book(s). The last two measurements was used determine the angle of the incline. Raise the incline by placing a second book under the end. Adjust the book so that distance, x, is the same as the previous reading. Repeated these steps with 3, 4 and 5 books.

At 1 second, the mousetrap car was traveling at a speed of 3.2m/s and as the mousetrap car moved down the track, at 5 seconds, the mousetrap car was traveling at a speed of only .98 m/s. The difference between the speed at 1 second (3.2 m/s) and 5 (.98 m/s) seconds was 2.22 m/s, the speed of the mousetrap car decreased 2.2 m/s as the car moved down the track. If I would’ve done this experiment at home, I would’ve improved it by letting one group go at a time because the noise from the other groups around the room interfered with our data once or twice. An experimental error that occurred during the lab was that once, the line on the graph increased at a smaller rate than the other trials. This was because we released the mousetrap car too early and because the car was father away from the motion detector at the start the motion detector picked up the car’s movement from 3 seconds to 5 seconds. Extension suggestions I have for a new experiment is, I would extend the trials so we would stop recording the positon the mousetrap car when the mousetrap would stay completely

The aim of the experiment is to examine how the acceleration of the car differs when the angle of inclination of the ramp is amplified and to record and analyse findings.

When constructing the mousetrap car, each team member had different ideas. The group considered each idea and included it into the construction of the car. Some team members wanted to test friction, by switching the wheels of the car. The group would test CD wheels and paper plate wheels. The group also wanted to test the axle gearing. The group wanted to test this to see if the speed would increase.The group also had tested the lever arm length, so the speed could be tested. The group tested different lengths, 5 inches and 10 inches. The group tested each of these

The device that displayed the best motion had three wheels. The reason that the device with three wheels displayed the best motion might have been due to the fact that it was the most secure out of the two. The device was much more even than the device with four wheels, holding the front tire in place and making sure it did not add more mass to one side than the other. The device with four wheels had multiple instances where the front tires would lean more to one side than the other. The average distance the three-wheeled device traveled was 888 cm while the four-wheeled device traveled 486 cm, a 402 cm difference between the averages.

My hypothesis is if the amount of wheels on the car is greater than, the car will travel farther, this hypothesis supports more wheels will travel farther on a car. Our hypothesis was not correct because if you have more wheels on a car the friction will slow the car down and make it go slower. The car with the most wheels traveled at an average of 79 cm and that was the worst out of all of the cars tested, the car with the most average wheels traveled the farthest in the experiment.

The car will change its speed when I change the incline of the ramp. I am changing the incline of the ramp to see and how the speed changes.

The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in

In addition, the stopping distance is longer considering the weight factor of the vehicle. Both these issues make this automobile very dangerous to the driver, passengers, other motorist, pedestrians, and small furry animals. On the other hand, the lower center of gravity that the car has to offer makes this vehicle less likely to roll over. There is also a shorter stopping distance for the car considering the weight of the car is much lighter.

A rightward moving rider gradually becomes an upward moving rider, then a leftward moving rider, then a downward moving rider, before finally becoming a rightward-moving rider once again. There is a continuing change in the direction of the rider as he/she will moves through the clothoid loop. A change in direction is one thing of an accelerating object. The rider also changes speed. As the rider begins to climb upward the loop, he/she begins to slow down. What we talked about suggests that an increase in height results in a decrease in kinetic energy and speed and a decrease in height results in an increase in kinetic energy and speed. So the rider experiences the greatest speeds at the bottom of the loop. The change in speed as the rider moves through the loop is the second part of acceleration which the riders experiences. A rider who moves through a circular loop with a constant speed, the acceleration is centripetal and towards the center of the circle. In this case of a rider moving through a noncircular loop at non-constant speed, the acceleration of the rider has two components. There is a component which is directed towards the center of the circle (ac) and relates itself to the direction change and the other component is directed tangent (at) to the track and relates itself to the car's change in speed. This tangential component would be

Speeding is defined as the act or an instance of driving, especially a motor vehicle, faster than is allowed by law. Speeding is often one component of aggressive driving which is defined as committing a combination of moving traffic offenses so as to endanger other persons or property. There are strong direct relationships between the speed at which we drive and the risk of crash involvement and the injuries sustained if a crash results. The probability of injury and the severity of those injuries increases exponentially with vehicle speed. Even small increases in speeds result in a large increase in the forces experienced by the vehicle occupants or other road users. Put simply, the faster you drive, the harder you hit and the more severe the injuries you or someone else are likely to suffer. Traveling over the speed limit can be especially dangerous in bad weather conditions. Speeding was a factor in 53 percent of fatal crashes that occurred when there was snow or slush on
