2. A 5000 kg roller coaster train is winched up the first hill, which is 80 m high. What is I) the speed of the train over the top of the second hill 70m off the ground and ii) the average breaking force needed to stop the train if it has 100 m to pull into the station?…
First, when you begin your ride it starts with a small inertia jerk, you can feel the exhilaration as you creep up the slope of the first hill at a constant speed. Whenever you get to the peak you can see an amazing view, and since you have the highest potential energy you get only a few seconds before you are going downhill at 100 miles per hour. Before long, as you come towards the bottom there are three loops, each 35 feet…
Suspense can be the point in which you are scared to death to keep riding, or the point in which you just want to get on with the excitement of the drop and flips. A roller coaster will either slowly pull the car up the tracks, making a clicking noise that…
The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy.…
Trade happened mainly among royalty. It involved the exchange of dried fish, wool, barley, wheat, and metal goods for sweet-smelling wood and fruit. Then these materials were passed down to lower classes of people who paid for these materials.…
First, to understand how a rollercoaster works, one must understand what exactly defines a rollercoaster. Generally, they have several drops and valleys, loops and turns, which are all traversed through the manipulation of its kinetic andpotential energy. For example, in most situations a roller coaster car will initially be pulled a large hill. As the suspense for the riders grows, so does the potential energy. Once at the top, the ride’s built up potential energy is turned into kinetic energy by the…
ball rolls down the hill, the potential energy is converted to kinetic energy as the ball picks up speed and…
As the height of the roller coaster increases, the speed of the marble decreases; and vice versa. When the height of the roller coaster is at it’s peak, the highest point, and the motion of the marble is going uphill; the speed has less kinetic energy than it has potential. The potential energy is being stored up, as the marble’s velocity is at an upward motion. Once the ball reaches the highest point and starts moving in a downwards motion, it releases the stored energy and gains kinetic energy. While the marble is in motion, both the potential and kinetic energy have to be balanced. For example : the top of the second hill contains a 50-50 relationship between kinetic and potential energy. As the ball goes downwards, the kinetic energy becomes more than the potential energy, and vise versa when the ball goes uphill. As an example, positions 1 and 5 are the positions that the object gains potential energy; the speed at position 1 is 38.31 cm/sec, and the following two speeds show the effects of kinetic energy. Position 2’s speed is 150.79 cm/sec and position 3’s speed is 180.95 cm/sec. On position 4, the object gains potential energy and loses kinetic energy because of the uphill motion, speed at position 4 is 155.74 cm/sec; and on position 5, the speed is 106.74 cm/sec. The change in these speeds show…
5. Describe the relationship between kinetic energy and gravitational potential energy as a roller coaster completes a trip.…
When we speak of “Morality” we think of the difference between right and wrong, the difference between the good and the evil. We use morality to justify our actions and decisions. More often than not, people impose their morality on others and expect them to act in the way they find fit. They believe that the idea of right and wrong is universal. In her essay “On Morality”, Didion contradicts this theory and believes that everyone can have different ideas of morality based on their own perception.…
600 years ago, roller coaster pioneers never would have imagined the advancements that have been made to create the roller coasters of today. The tallest and fastest roller coaster in the world is the Kingda Ka, a coaster in New Jersey that launches its passengers from zero to 128 miles per hour in 3.5 seconds (most sports cars take over four seconds to get to just 60 miles per hour). It then heaves its riders skyward at a 90-degree angle (straight up) until it reaches a height of 456 feet, over one and a half football fields, above the ground, before dropping another 418 feet (Coaster Grotto "Kingda Ka"). With that said, roller coasters are about more than just speed and height, they are…
Mechanical energy was the last thing that happened in the movie. Mechanical energy was happening when the toy train was moving. This was happening because the energy from the train was transferred to the train tracks it was on. There was also many different things in the movie that included mechanical energy.…
The roller coaster is so fast. It is a roller coaster that is never seen before. When you see some roller coaster have some loops and small turns, well this is the complete opposite. Consequently, You will experience so much during the ride and what is even better is if you chose to ride in a cart that will go twice around for a little bit more so you do not have to wait in line again to ride it another time. The carts are aerodynamic so that he has less air resistance they will have a higher speed. I personally like roller coasters that are fast so with this being more aerodynamic which will allow it not to slow down while allowing it to not decrease in speed. When you are going down the hill you will always feel weightlessness which is when you lift out of your seat like you're flying. It has an acceleration…
The stand up roller coasters can feature different designs like vertical loops, incline loops, corkscrews, and dive loops. Some roller coasters that you can find today are either closed or are still operated like the Cobra or Green…
[4] After the roller coaster is drops from the first hill it does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic…
