Kinetic Energy: Stopping Distance Of A Small Vehicle

My research question is about how the laws of motion apply to automobiles. I am interested in this research question because people do not realize how knowing the laws of motion can help on preventing a car accident. By having the knowledge of these laws of motion, people can understand why engineers make the cars like they do. The question and importance of the use of the seat belt can be answered. People can now understand why speed limits are used. Also, they can know why some cars accelerate faster than the others. All these questions can be answered with the three laws of motion. It can go from the use of the seat belt to the very bottom of the creation of the car. Knowing the laws of motion can help understand the effects that can occur with actions like not putting the seat belt on. There are three laws of motion described by Isaac Newton which are basically about forces and motions. Isaac Newton was a mathematician, scientist, and physician. The first law of motion is mostly recognized as “The Law of Inertia”. The second law of motion is the law that states that the force used in order to accelerate an object depends on the mass of said object. The more the mass the more force that is needed in order to accelerate said object. Also, the ones who are the ones to build race cars try to make the cars smaller and the mass of the engines a lot less than the regular cars. This is the reason why when the race car crashes there is not much within the car because the more

Where ρ is the density of air, A is the cross-sectional area of the rider&bike, v is the velocity, and D is

#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

Many things can’t be explained, but I have explained a few things that might seem confusing. If distance equals rate times time, than how fast the object is going, and how long the object is staying in the air is key. The machine that works faster and keeps the object in the air longer should be better than the other. Unless there is a difference in the objects, as such as one might be lighter, or float to stay in the air longer. Or if one object is more aerodynamic than the other.

The more weights added to the car the faster the car goes. Our mass hypothesis, if the weight of the hot wheel decreases then the speed of the hot wheel increases. Our hypothesis is incorrect, we said the more weights you add the speed of the hot wheel will decrease, the data my group collected tells us the opposite the more weights you add the speed of the hot wheel will increase. Our hypothesis on road surface was, if the roughness of the road increases then the speed of the car decreases. This hypothesis was also incorrect, our data tells us that changing the road surface increased speed instead of decreasing it. Changing road surface and weight increased the speed of the hot wheel car. Our data we collected could have been affected by not placing the car at the same spot every time or not stopping the stopwatch fast enough. Our procedures did change during testing, we were going to stop the stopwatch once the back wheels were at the end of the track, we changed that because we wanted accurate times so we extended the stopping length 40 cm. In conclusion, if I were to do this experiment again, I would make sure I stop the stopwatch on

Near the top of the ramp, the car’s speed was around 102 centimeters per second. In the middle of the ramp, the car’s speed was around 156 centimeters per second and near the end of the ramp, the car’s speed was around 196 centimeters per second. No one in the group pushed the car at any time. The slope of the ramp was also constant the entire time. There had to be an explanation for why the car’s speed was faster as the car went on. What we came up with was that as the car traveled down the ramp, it picked up speed. Once we plotted these points on the graph, it was extremely evident that this was in fact what had happened. The graph clearly showed that the speed of the car was increasing as it went down the

The purpose of conducting this scientific investigation was to see if the size of a wheel on a bike effected speed. The hypothesis for this project was if the wheel on a is bigger than the other wheel’s then it will be the faster. The independent (IV) variable was the wheel size. The dependent (DV) variable was the speed. The way the responding or dependent variable was measured was by starting a stopwatch right when the bikeer started biking and stopping it after doing four laps (1/4th of a mile). The results of this experiment were 1:19 for the biggest bike, 1:18 for the control group bike, and 1:17 for the smaller wheeled bike (minutes:seconds). The results of this investigation show that the hypothesis should be accepted.

Newton’s first law of motion states that an object will remain at rest, or will continue with a constant velocity, unless an unbalanced force acts upon it. When a car comes to an abrupt stop, the passenger moves forward and stays in this motion until an unbalanced force acts upon it. The seatbelt

Our prediction states that when the ramp is angled more, the car will travel faster and our data shows that when the ramp is 15 cm, the car travels the fastest. The data states that when the ramp is angled at a 3 cm height, the car travels at the speed of 34.64 cm/s and took 1.79 seconds to travel 62 cm. While the speed of the toy car is 213.8 cm/s when the ramp is angled at 15 cm. The ramp heights at 6 cm, 9 cm, and 12 cm all follow between the ranges of approximately 33.7 cm/s to 248 cm/s, each speed increasing as another 3 centimeters was added. The greatest acceleration is shown at 992 cm/s/s by a car traveling the ramp height of 15 cm and the lowest acceleration of 18.32 cm/s/s at a 3 cm ramp height. The data shows that when the ramp is

Regenerative braking is stored by converting the vehicle’s kinetic energy into a chemical energy in the battery.That stored up energy will now or later be used to power that vehicle to drive.The energy that you recover depends on how far you drive and where you drive.Energy is converted to DC and then to AC.The energy required to rotate the motor slows the car down.Greater stopping force means greater power generation.

We just need to figure out a way to keep the wheels on the car balanced while it is going. We will try taping the wheels to the axle to fix this problem. Wheel alignment is very important because we want our car to go straight, and wheel alignment will help to prevent the car from collapsing. We also need to find a way so the axle on the car spins faster so we can move farther quicker. Right now the friction with the axle and the cardboard is making it impossible for it to spin fast enough to propel the car. We will try putting our axles through straws to fix this

An experiment was performed to determine the velocity of a toy car traveling in a straight line. A toy buggy car was set in motion and a marker was placed to indicate the location of the car every 2 seconds as measured on a stopwatch. The displacement of each marker from the starting point was measured using several meter sticks. This measurement was repeated using the same car 5 times. The average displacement and average deviation were calculated using Google Sheets, and the average displacement was plotted against time. The resulting graph appeared linear and the slope of the line was used to determine the velocity of the car. The velocity of the car was determined to be 0.38 ± 0.04 ms-1. An accepted value for the speed of the car was

In our life, what the one thing we will be in more than our beloved home, our vehicles. For most of us, the vehicle is the most important transportation devices within our modern life. Whether you are taking a bus, carpooling, or driving your own car, we can all share this common action that among us. And for this reason, that I decided to do my research paper on the automobiles and law of motion. Most of us that drive or have been in a moving vehicle doesn’t know much of the physic behind it. Like when you press the gas pedal why does the car go forward, or what force is behind it. When you press the brake, does the car just add negative acceleration or the wheel just stop moving. How come you can’t do certain thing in a civilian car, but can do other thing in like a drift car or race car. Knowing the physic behind our second home, can be beneficial if something breaks down. Because knowing the relativity of our machine, can prevent us from being over charged when going to a repair shop. Isaac newton law of motion help explain this modern era important invention that transformed the human races from horseback riding to vehicle driven. The main reason why I picked this topic is because, of how much modern vehicle have been part of our life. The vehicle is no longer just an item, but it is part of our lives, part of our family, if something were happen to it we would feel depressed and sad. If you have ever have been involved in a car accident you know the

2. These questions were not that hard at first because I thought we were just solving for kinetic energy. But when I saw the km/h and had no idea what to do with it because I never remembered working with it in the past. So I randomly multiplied the 30km/h in my head without showing the work because I was so lost and was running out of time. But I do understand now why we did not do anything with the 30km/h. We did not do anything with the 30km/h because it was just a reference point for us. And to figure out kinetic energy, you cannot add the speed at
