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?…
some of the energy is converted to heat, which is not a very usable form of kinetic energy.…
Energy may be either potential or kinetic. Potential energy (PE) is energy stored and ready for use. A car stopped at the top of a hill and a water balloon dangling out of an upstairs window have potential energy. Potential energy is measured by the amount of work the object can perform. The other form of energy is kinetic energy (KE). Kinetic energy is the energy of motion. A car rolling downhill and a water balloon falling towards its target have kinetic energy. Because of its greater mass, a falling car has more kinetic energy than a falling water balloon. Similarly, because of its greater velocity, as water balloon that is thrown down will have more kinetic energy than one that is simply dropped from the same height. As these examples show, potential energy can become kinetic energy. Kinetic energy can also be transferred from one object to another: imagine a car or the water balloon striking a ping pong ball and sending it flying. Recall also that kinetic energy comes in six forms - chemical, electrical, radiant, mechanical, nuclear, and thermal- and that each of these forms can be converted into any of the other forms. For example, a battery converts chemical energy into electricity, and a light bulb converts electricity into light and heat.…
When it is on its way up, it is using kinetic energy since the energy is in motion. When it reaches the top it has potential energy. When it goes down the hill it is using kinetic energy again, this is a simple easy understanding of how they change from one from to another. An example of potential energy within the body lays in adipose tissue, potential energy waiting to be used during exercise, such as running or kicking a ball. Kinetic energy is physical movement in the body every moving objects has kinetic energy.…
All vehicles have a mass to the order of a few hundred pounds. When our vehicles move at a certain speed down the road, they create an energy by the property of their mass and forward velocity. This energy is called Kinetic Energy. Assuming the mass of a vehicle is assumed to be constant, it will create a certain quantity of kinetic energy while in motion at speed. When a…
The amount of potential energy the structure withheld on the top of the hill, released a great amount of kinetic energy; which then impacted the force of gravity on the marble. The amount of energy that the marble gained from potential energy, was released and balanced with kinetic energy. Approximately 90% of the energy on the marble was kinetic energy, and the other 10% was potential. Previously ending its route, the marble’s potential energy was no longer of great use, as in the marble did not use above 99.99 % of its kinetic…
Potential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.…
Kinematics is motion. We are in a world full of motion. You jump up, and there is a counteracting force that will move you down. Drop a ball, and the ball will fall to the ground. Push on a shopping cart, and the cart moves forward. These are all examples of motion, but there is a lot more to it than just being at rest or being in motion. One example of kinematics in the real world is in roller coasters, a thrill-seeking pastime for many.…
Kinetic energy is the energy of object in motion. Potential energy is the energy a object has due to its position or traits.…
5. Describe the relationship between kinetic energy and gravitational potential energy as a roller coaster completes a trip.…
There are two types of energy conversion, potential and kinetic. Potential energy can be converted to kinetic and vice versa (Tillery, Enger, & Ross, 2009, p. 63). Any form of energy can be converted to another form of energy. Energy conversion is evident in the following conversions-a light bulb converts electrical energy into radiant energy and a car converts chemical energy into mechanical energy.…
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…
Energy is provided by food and drink. It comes from the fat, carbohydrate, protein and alcohol the diet contains.…
[1]The rollercoaster car gains gravitational potential energy (GPE) as it travels to the top. Once over the top, the car gains speed as GPE is transferred to kinetic energy (KE). As it travels to the top of another loop, KE is transferred to GPE. Not all the energy is transferred to or from GPE – some is transferred to the surroundings as heat and sound. All moving objects have kinetic energy, KE. The kinetic energy an object has depends on the mass and speed. If the mass doubles, the KE doubles and if the speed doubles, the KE quadruples. Normally energy is lost through sound and heat (friction, air resistance).…
