Car A, Car C, and Control Car followed the same pattern of increasing as the Trials went on. Car B and Car D had certain spikes of decreasing and increasing time. Each car was placed with the wheels between the block of wood and let go when the stopwatch was started. Then the data was carefully charted before moving on to the next trial. The IPhone 4S stopwatch app may have been an extraneous variable because of the way it measures time may be different than a standard stopwatch.
When they extricated car from the hood, I had never seen an entire crowd, so excited about the speed of a car in my entire life. The primary characteristic of a car should be the fun factor. What made it so much more interesting than the car is simple: a great fun factor concept. When there is a unique fun factor, the car is ultimately better, and these fun factor concepts have similar qualities. The biggest factor of a good sports car would be the speed of the car.
Do people like horsepower? Do civilians prefer to have their car going fast? Many people who like their cars going fast don’t really know everything they need to know to get their car to go fast which would be the aerodynamics or “the way air moves around things” drag racing cars are built so they don’t have a lot of drag and they can dart down the track . Drag is a force that acts parallel and is the same direction on airflow drag impacts on how the automobile passes through the air. It’s kind of ironic how they don’t want drag on the car, but it’s drag racing.
Speed relates to a roller coaster because gravity is pulling the cart down hill making its speed increase to go faster. Velocity relates to this design challenge because a ride can move at a constant speed but its velocity is constantly changing when its direction of motion changes. Newton's First Law of Motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This relates to this design challenge because when a roller coaster starts as a drop it wants to continue moving in the same direction. It does not however because the tracks act as a force and change the coaster's direction.
Harald Belker, designer of cars for real life and fantasy once said, “You can have a two-seater where the passengers face each other,.” (Driverless cars are leaving cities in the dust, report says) Without always having the need to keep eyes on the road, cars would be able to change around seating to possibly face each other, rather than traditional forward facing seats. Another way cars will be changed is by installing new technology. For an automobile to not require a human driver, much newer technology will need to be installed in new cars. One last way cars can be changed is by completely redesigning the car. With interior movements and no need for things such as a clear windshield, cars will be able to be created so that they are possibly more aerodynamic which will help reduce things like gas usage.
Let the person with the stopwatch count down. 8. Then after the count down the person releases the trolley. 9. After the trolley’s rear wheels leaves inclined surface stop the stop watch.
So why not speed in cars too? In my opinion, Speed limits should be definitely raised. Accidents do not happen just because of speeding in fact they happen because of people that are reckless, irresponsible and immature. They are thoughtless in controlling their speed. Raising the speed limits would benefit the society in many different perspectives.
This will increase the safety. In other words by increasing the time of the collision, the force of the collision is reduced. This graph shows us that the number of the facilities from cars has reduced because of all the safety
The reason for this is that it is desirable to avoid discontinuities in the force exerted on the car. Since a component of that force comes from centripetal acceleration, which is directly proportional to the curvature, the curvature must remain continuous. A discontinuity would not only be uncomfortable for the rider. We want a curve that is fun to travel along, which means sharp curves—but not too sharp, unless we want our amusement park guests to get sick or pass out. The distance a roller coaster car has traveled along the track will be denoted as S, while the distance a car has traveled into an element will be denoted s. The total length of an element is denoted by s_i where the subscript i denotes the number of the element in the ordered set.
Improvements Improvements can be done to minimize the effect of errors so that the experiment results will be more precise and accurate in the future. Random Errors In order to reduce random errors which is caused by reaction time when taking stopwatch reading we will be more careful in planning of experiment. Instead of letting only one people to count and take the reading of the revolution of the rubber stopper at the same time, two people will be assigned for it so that the reading will become more accurate. This will help people in charge to count the number of revolutions to concentrate fully on the revolution while people who is controlling the stopwatch can concentrate fully when to start and stop the stopwatch. This can prevent from
