Investigation on Collision of a Car with a Wall Personal Engagement and Exploration Background information
In the automobile industry, Crash Test[1] is an experiment conducted by car manufacturers to enhance safety for passengers. In such tests, an accelerometer, and a force sensor are usually used. These devices allow experimenters to collect relevant data, such as the acceleration of the car, the velocity upon impact, the time of impact, the forces applied on the vehicle and the dummy. The data collected from these tests will be used to improve the design of the vehicle, as well as the details on the airbag, which is a shock absorber installed in cars.
There are a few types of Crash Test available[2]. The one that many people know of is

Drivers and passengers, as well as pedestrians, have a higher chance of survival in the event of collision. Problem Statement
This experiment will investigate the relationship between the force exerted by a car of fixed mass on a stationary solid wall and the velocity of the car upon collision. Application of Crash Test in this experiment
In this experiment, the type of Crash Test applied is the Frontal-impact test[3]. However, the test will be altered, by allowing the car to collide at different velocities.
In this experiment, the equations below will be used to find the velocity upon impact:
F_(C-W)=ma [4]
v^2=u^2+2as

Firstly, the cart was weighed using the electronic mass balance. The mass was recorded. A distance of 0.500 m was measured using the metre rule, from the tip of the force sensor to the tip of the cart, as shown in Diagram 1. The point was marked using a pencil. The force sensor, connected to the interface and the computer, was placed at the end stop, and then it was calibrated. The end without the end stop of the track was clamped. The height of the clamp was adjusted so that the angle of inclination is 5.0o. The sensor was allowed to start collecting data. The cart was placed at the marked position. It was then released. The data collection ended when the cart touched the sensor. The Force-Time of the first trial was then exported. The experiment was repeated twice for each angle of inclination. The experiment was also repeated at five more angles of inclination, 10.0o, 15.0o, 20.0o, 25.0o and
In the film Crash, a voice over says: “We're always behind this metal and glass. I think we miss that touch so much that we crash into one another just to feel something.” Crash is a mirror and reflection of who we are as individuals. There are many tasks we each have to do in our daily lives, and we encounter many people without realizing that we are connected. The results of these social interactions are often with violence, racial discrimination, and power struggles. We begin to judge people on their common appearances and begin to group them. Stereotyping and the misperception of people create these conflicts and ruins our society today, just like a car crash.
Directly after the video she asked them how fast they believed the cars were going. Each time she used a different word to describe the two cars interaction from collided, to smash, to hit. When she used a more intense word, like smashed or collided, the participants guessed much higher speeds. One week later she then asked everyone if there was glass at the scene. Most
Many physics principles apply to a mousetrap race car, although it is a simple device. A mousetrap car is very simple to make because it can be created using several different materials and methods. Both of these laws prove that the more massive the mousetrap car, the more force that will be required to move the car. The mousetrap car works by transferring the spring’s energy to the car’s wheels. Friction acts in many ways while the mousetrap car is moving. All of these principles allow the mousetrap race car to function and should be considered when creating a mousetrap car.
“How about we use a pulley system with a weight at the end to push the car forward?” my team member suggested. “Or we could use a hammer launcher,” I proposed. We went back and forth, contemplating different methods. We faced trials, tribulations, and troubles in the design process. Building and perfecting our designs took weeks, but our coach guided us throughout the process and encouraged us to “Never give up!” We researched the effects of different factors that could potentially come in the way of our success and analyzed all of the device possibilities. Even when research got arduous and we couldn’t agree on something, we never gave up on our dream of placing in the regional competition. This was one of the hardest challenges I’ve ever faced in my Science Olympiad career, but our unfaltering dedication and our belief in success helped us persist in the face of setbacks. Once we finished our plan, we began to build the device. It was exhilarating to see our plan come to
The most predominate theme that occurred throughout Crash is that “human aren’t all bad” (Farris 357). The movie effectively depicted the theme by showing every characters’ situation from their perspective. Officer Ryan is a good example. Ryan was originally portrayed as a bad guy for molesting Christine and being racist when he pulled over the Thayer’s car. Ryan wishes to see the suffering of others during this specific scene, because he was suffering and agitated from not being able to get proper medical treatment for his father. In other words, Ryan did not act fully out of malicious intentions, but rather he wants to release his stress and anger upon someone else. Later in the movie, it is shown that Ryan was not a real racist since he
Imagine that your car could detect hazardous roads before you could sense it? A feature that provides this type of protective driving exists within European cars. This valuable safety feature that is offered in European cars i...
The first thing my group did was confirm our method of taking data and who would be doing it as well as defining out independent and dependent variables. Since we would be directly controlling the net force we made that our independent variable which left the acceleration as our dependent variable because it was a factor that varying as a result of our net force. We weighed our cart with every single mass in it along with the string and the hook which turned out to be 1.97kg. We did not add anything else to our system after this to keep the mass of the whole system constant. Our setup was like this: a ramp was sitting on top of the table, parallel to it so it had no slant. On one end of the ramp, a pulley was attached. On the other side of the ramp, a motion sensor was set up so it faced directly down the path of the
In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
Appendix: page 13. Rubric: page 14. Introduction: Grade 12 Physical Science learners at Penryn College were tasked with carrying out an experiment to investigate the effect of collisions on momentum. Different mass pieces (500g; 1kg and 1.5kg) were dropped on a moving trolley and the learners observed the velocity of the trolley before the mass pieces were dropped on the trolley and the velocity after the mass pieces were dropped.
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.
Nobody goes onto the roads with a hope to die, we all want to come home to your families. This will be if we drive safely. Safe driving should come from within us and it is very much possible to prevent the road crushes that are being reported every now and then, occurring from mere destructions (2). Safe
author build car with suitable cockpit to evaluate steering response curve and proper physical behavior of the car to give realistic experiment. with this setup author has conducted experiments on different linear and non linear steering response curves to find out suitable steering system for passenger car. After study author come on conclusion that linear response curve with a high steering ratio like 1:45 or 1:60 lead to the least amount of lateral velocity of the car at speed of 200km/h and this will lead to complete crash due to loss of control on
There are many social problems that exist in the world today, which includes but do not limits to self-identity and racism. However, they somehow go unnoticed because at times people conform to what society thinks is the way to live. In my opinion, people believe they should act or feel a certain way because of what is broadcast on television, featured in magazines, and even brought into the limelight by celebrities. After viewing the movie Crash, in my opinion, the movie targets on going social problems that are constantly being swept under the rug to this present day. I deem Crash a race movie because it forces the audience to question their own moral values.
For all these features any car can still crash so this report aims to make you more aware of the safety aspects of modern cars and what role they play in driving.
Law two can be used to calculate “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” This formula is used in all of the above components in the car.
