The purpose of the lab is to find the change in velocity and acceleration of the toy car. We predicted that as the distance the car will travel the longer it will take to get there. We also predicted that graphs for speed and acceleration will be the same and will have a constant motion. After taking data and recording the different trials our prediction was sort of true. As the distance increases the time increases as well. For example 60 cm took an average of 1.28 seconds, 70 cm took an average of 1.508 seconds, 80 cm took an average of 1.89 seconds, 90 cm took an average of 2.076 seconds, and 100 cm took an average of 2.34. We were correct when we predicted that the graph for speed and acceleration would both have a constant motion because
Our predicted points for our data are, (13, -88.57) and (-2, -29.84). These points show the
For my derivative project I chose to graph Emmitt Smith’s annual rushing yard total. Emmitt was drafted out of University Florida in 1990 and began his career as an NFL Great. As you can see on the graph, Smith began his career slowly, amassing only 937 rushing yards his rookie year. However, his second year Smith improved to 1563 rushing yards. In his third season, Smith again improved to 1713 rushing yards. The decrease in production Smith’s fourth and fifth year (1486 and 1494 respectively) in the NFL can be partially credited to the fact Smith did not compete in all sixteen regular season games due to injuries. Smith redeemed himself the following year with a career high 1773 rushing yards. Over the next six years Smith’s age slowly caught up to him as he ranged from 1021 to 1397 yards. Finally, after his thirteenth year as a Dallas Cowboy, Smith was traded to the Arizona Cardinals. In his first year with the Arizona Cardinals (2003), Smith was injured and played as a backup for the majority of the year. This is illustrated through his career low 256 rushing yards. However, in Smith’s final year in the NFL, he rushed for 937 rushing yards, bouncing back from a disappointing year. Strangely, Smith ended his last season with the same rushing total as his rookie season. I plotted these points in a graph in an excel document and created a line of best fit. This line was a cubic equation (f(x) = 1.4228x3 - 8533.3x2 + 2E+07x - 1E+10).
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration. the following points: -Fair testing -Equipment -How many results will I get? -What range of variables I will experiment with I will be investigating, by varying the height of the summit of the ramp. is raised off the ground, if the average speed increases or decreases.
While designing a particular vehicle of a particular class, there are some atributes and protocols to be followed. Because the designing and the procedures change from car to car.
All three of Newton's laws apply to the balloon car. Since it slows down Newton’s first law is affecting the car. The law states the car would keep moving at a constant speed unless another force acts on it. The force of friction is acting on the car which is the other force that slows it down. Newton’s second law was able to help make the car. The law states that if mass goes up acceleration goes down and vice versa. Since the mass of the car was low, the car was able to gain a lot of acceleration to move it along. Lastly, Newton's third law applies to the car because when the the balloon pushes the air out of the car the air pushes back on the balloon. Since the balloon is part of the car the air is pushing our car along the track with applied
The power regression seems to be the better model for the experiment that I have
Toy Story is the groundbreaking 1995 motion picture developed by Disney and Pixar and directed by John Lasseter. The film was so revolutionary not only because it was the first feature length animation to be created completely by CGI (Computer Generated Imagery) but also, also the film was more rounded in all respects. The characters not only looked more sophisticated and three-dimensional but their personalities were also more human and fewer cartoons like. The film uses a constructed text in order to put across a theme of two very different characters learning to work together beyond their rivalries to rise above a common enemy and work towards a common goal. The film uses characters and imagery very cleverly to portray this theme. The music used in the film is also different to other Disney features. Rather than the characters bursting into song themselves as in Aladdin or Hercules, the songs are played and sung by an outside person (Randy Newman) and reflect the mood and emotions of the characters in a particular scene. For example, the title sequence song “Friend in Me”, when Woody and Andy are playing together, and the scene where Andy’s room has been made over to a Buzz Lightyear theme, “Strange Things” where the song reflects Woody’s confusion and fear not only about the change in his surroundings but also the change in his friends and his own character and self-confidence. The attention to the smallest detail for example the reflections in Buzz’s visor give the film even more realism and depth. The use of unusual and imaginative camera angles, made possible by the use of CGI, also adds to the texture and pace of the film.
Force is a push or a pull, which can make an object start moving when
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 reasonable control.
This only tells us the average rate of speed. To find the exact speed the car was going when it crossed the finished line, approximate it by finding the slope of the line between the point we want, in this case, (6, 1320), and a point closer to it along the curve. As we move the secant line closer and closer, the slope changes and gets closer and closer to the instantaneous speed. By doing this, mathematicians discovered that the slope of the line tangent to the point is the instantaneous rate of change. So to find the speed of the dragster as it crossed the finished line, we can use the slope of the line tangent to the point of the finish line. Th...
Three line graphs have been created to see a trend in the recorded data of heart rate and blood pressure. The purpose of the line graphs it to observe the trend. To take the measurements recorded and apply a visual image. The p-value for figure one calculates to be P=0.35. Next, the second line graph p-value calculates to be P=0.06. Finally, the last line graphs p-value calculates to be P=.57. In all three graphs, you can see a spike from the basal reading into the ‘during’ time frame. In both blood pressure, you are can see a decline from ‘during’ to ‘4 minutes
Safety changes are not only changes within the racecar or to what the drivers wear, there have also been changes to the walls that surround the tracks. Many officials realized that there was an increase in high impact crashes into walls (Aumann). In the article, “SAFETY IMPROVEMENTS, CHANGES DEFINE RACING ERAS”, Aumann states, “Indianapolis Motor Speedway president Tony George began looking for a solution”. There were many attempts to create a safer wall. The first attempt, “was designed by retired General Motors engineer John Pierce and placed on an interior wall near the entrance to pit road in 1998” (Aumann). This was put into use during the International Race of Champions when a driver struck the wall. the driver was not seriously injured,
Statement of the Problem: RC cars are usually hard to control if you are using one hand. This difficulty occurs because of its design and shape. I plan on making a hand glove that can control RC cars using just one hand with the movement of your fingers. Purpose of the Study Normal RC cars usually take two hands to navigate and drive the car using the remote. By developing this hand glove, the requirement for the control over the RC car would be reduced to just one hand rather than two.
