Different Types of Energy Essay

Neither Timber Terror nor Tremors has an engine or anything pushing the cars along the track. The only time the cars are aided by a machine is when the car is being carried to the top of the first hill and the compression brakes at the end, but from then on, the cars are in the hands of potential energy and kinetic energy (“Roller Coaster”). Mechanical energy is used to lift the train cars to the top of the hill. Once it reaches the top of the hill, the car has a very large amount of potential energy. After the car reaches the top and begins its descent, it loses potential energy with the loss of height and gains kinetic energy. Each time the coaster goes up a hill, it loses kinetic energy and gains potential energy (“Energy Transformation”). Although potential and kinetic energy play the largest roles in the physics behind a

As the car go down it looses its potential energy because it is not at the same height anymore. As it loses the potential energy it gains kinetic energy. Kinetic energy came along because of its high speed. The mathematical equation for this is initial kinetic energy plus initial potential energy plus external work equals final kinetic energy plus final potential energy. To find work the equation is force times distance. To find power the equation is work divided by time.

I will start with the beginning, which is the ramp and marble. We used a marble that had more mass than the others. We did this to give the marble more potential energy. We set the marble at the top of the ramp, which gave it more potential energy as well, and released the marble. Once dropping it, it's previous potential energy transferred into kenetic energy. After this step came the metal lid. What this step showed was rolling friction and it also pushed it forward. How exactly? Well, when the marble landed, it bounced up, giving it elastic-type energy. It then fell, making it roll across the top of the lid the rest of the

The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.

a) When the lever is winded up and all set for release the Mousetrap Car (MTP) has potential energy that will be used to accelerate the car. 2) When the lever is released the string is pulled from its ready position on the axle causing the level to pull the string causing a pulling force on the string by the lever. 3) When the lever is released and the string is pulled the back wheels of the MTC are beginning to move because of the potential energy that is now kinetic energy which causes rolling friction between the Mousetrap Cars wheels and the ground. 4) The MTC is now accelerating at a certain speed from it's point with the string being pulled by the lever until the spring is snapped, which then causes the MTC to

(There are a few roller coasters in the world that use engines to move them, and most are children attractions) The change from potential to kinetic energy is what moves the roller coaster. The potential energy is the type of energy that is first stored and then transformed into kinetic

　　Our prototype car did perform as desired. So we made improvements by, making the vehicle longer, replacing a crayola pencil with a fishing rod, and creating a wall to store more potential energy by bending creating a spring-like motion with the fishing rod. We put the aluminum tubing inside the wooden frame. Then, we put the graphite in the aluminum tubing and put the axles in the tubing with the

Place 1 steel orb in the toy car and hold the car against the wooden stop closest to the physics stand on the ramp and release the car.

The Effect of the Steepness of a Ramp on the Velocity of a Toy Car

1. A toy car starts travelling to the right in Figure 2 from the origin from rest. Figure 1 shows its driving force against the distance away from the origin in the first part of its journey. The surface to the right of the origin is frictionless. Assume no air resistance for this question.

The car starts with potential gravitational energy and ends with kinetic energy, so: PEg = KE (1) Equation one then becomes represented by Equation 2 by substituting what each energy is equal to. mgh = .5mv2 (2)

To start of with a positive note, what worked well with the balloon car was the lightness and actually moving. The wheels did turn- which was something I was not expecting and went in a fairly straight line. Now what did not work well was it has too much mass. Unfortunately the car did not go as far as I hoped it to go. Next time- if there is a next time I will make the body and wheels lighter. I also learned the more you blow up the balloon the less force it will exert. I learned many new skills and learned you can’t always accomplish what you hoped to achieve.

The car uses 4 forces. The 1st force is weight,which may change the speed in which the car can

The cars on a typical roller coaster are not self-powered. A standard full circuit coaster is pulled up with a chain or cable along the lift hill to the first peak of the coaster track. The potential energy accumulated by the rise in height is transferred to kinetic energy as the cars race down the first downward slope. Kinetic energy is then converted back into potential energy as the train moves up again to the second peak. This hill is necessarily lower, as some mechanical energy is lost to friction. Not all rides feature a lift hill, however. The train may be set into motion by

The bigger the mass of the toy car is, the more frictions it will create while rolling down the ramp and therefore the more unbalanced force and speed bumps it will face and slowing it down. So an object with smaller mass will travel much faster than an object with a bigger mass on the same angled ramp.The reason for is hypothesis is that the bigger the mass of an object is, the more contact it will have on the surface of the ramp, therefore creating more frictions. When two solid surfaces (one moving and one still or both moving) make contact with each other and is created frictions. The more friction there is, the slower an object will travel and the quicker an object will
