Kinetic energy

gravitational energy in the counterweight. This is turned into kinetic energy as the counterweight falls. Since the law of the conservation of energy states that the energy has to go somewhere, the energy in the counterweight also needs to go somewhere. In the instance of the Trebuchet, the kinetic energy in the counterweight is transferred along the throwing arm and into the projectile. When the projectile is fired, it travels upwards as well as forwards. This causes some of the kinetic…

Wind Energy and Dynamics Today many forms of energy exist that assist in creating power to be used on the industrial and commercial level, as well as power the many buildings that reside throughout the United States and the rest of the world. While there are an immense amount of methods that produce power/energy, one of the more recent developments pertains to that of wind energy. Wind energy is considered a renewable energy source because wind is always in supply, whereas fossil fuels such as…

Instead, potential energy is stored in things like ropes until the catapult is ready to fire, when the energy transfers to the projectile and become kinetic. The three primary energy storage mechanisms are tension, torsion, and gravity. The catapult has proven to be a very effective weapon during ancient times, capable of inflicting great damage. The…

Aim: To investigate the changes of velocity and to investigate the acceleration and of the car. Also to investigate to see if the velocity and the angle of the wooden plank would make the severity of the crash increase. Hypothesis: The higher the slope of the wooden plank, the faster the car will go therefore the increase of the severity of the crash. Variables: Independent Variable – The height of the ramp Dependent Variable – Distance that the dummy flies – the velocity of the car Constant…

Hydroelectric energy is made from a turbine that turns falling water into mechanical energy; then that mechanical energy is turned into electric energy. This process helps produce electric energy from the kinetic energy of falling water. How does this process involve chemistry? It first begins with the mechanical energy of the water. Mechanical energy is all the energy that is put upon an object. In the case of the hydroelectric generator, the mechanical energy is made from the position of…

defined as the average amount of kinetic energy that an object has. When an object has a great amount of kinetic energy, then its molecules move around a lot. This can be explained by thermal energy, or heat. Heat is produced when internal energy travels from an area of relatively high temperature to an area of relatively low temperature. This internal energy is then called thermal energy. Higher temperatures are associated with higher amounts of thermal energy and thermal expansion.…

completely met and that I might need to change my routine in order to feel satisfied with the goals I want to accomplish in life. As I look at my elements I see that I am focusing my energy mainly in school, which is acceptable since this will help me fulfill my goals of having a successful career one day. School is a positive energy and it brings me satisfaction when I finish a term with a good grade, but at the same time it can be depleting. I have to focus and give most of my time to school…

inside the water park. The roller coaster, is filled with many twists, turns, and loops. This roller coaster is not just any roller coaster, it has a fabulous view of the whole park. The tallest point on this ride, where you feel the highest potential energy, is over 4,586 feet tall. This ride is over four football fields long!! While you are waiting in line you can see that the cars have three rows and in each row there are eight seats. The coaster cars you see as the buckles come over your…
