Different Types of Energy Essay

On a larger scale, the example of a Lego made motors efficiency can relate to that of a modern day car and the efficiency / energy waste that comes from it. The internal combustion engine is an engine in which the combustion of a fossil fuel mixes with air in a chamber of the operational fluid flow circuit.

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.

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

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

We will look at the roller coaster. This is possibly one of the main attractions at an amusement park. What many people don't recognize is the fact that roller coasters aren't propelled by an engine. There is a good reason to back up the fact that the first hill is always the highest. Once the coaster is pulled up the hill by the crank, potential energy is at its fullest. As the coaster is making its way down the hill, that potential energy is converted into kinetic energy. At the bottom of the hill, kinetic energy is at its highest. Throughout the rest of the ride, the coaster is simply propelled by the constant conversion from potential to kinetic energy and back again. Another factor that enters into the extreme speeds that roller coaster

　　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

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 experiment was conducted in order to investigate the gravitational potential energy (GPE) and kinetic energy changes, as a car progresses down a rollercoaster track. Throughout a rollercoaster ride, the laws of physics are always involved. These include simple inertial, centripetal and gravitational forces. In the initial ascent of a rollercoaster, gravitational potential energy is gathered and as the rollercoaster descends, this energy is converted into kinetic energy.

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.

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 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)

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

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