Chemical kinetics

Kinetic energy comes from the relationship between the mass of the object in motion and its velocity. This energy has to be converted from another form of energy as the law of conservation of energy states that energy can not be created or destroyed only…

dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United States and China for the coming decades?”.…

1. What energy system(s) does the Wingate Test rely? Explain. The energy systems that the Wingate test relies on, is glycolysis and ATP-PCr. Anaerobic power is used for high intensity, short duration exercises, and activities. The Wingate test is anaerobic, which will utilize fuel through glycolysis and the ATP-PCr system. The Wingate test is very short in duration, and high in intensity, which means oxygen is not present in this process. The ATP-PCr system breaks down ATP into ADP for energy.…

gymnast. To begin, there is the running start; this is where energy plays a major role. During a gymnast’s running start for a vault, she gains kinetic energy, which is, simply put, the energy of motion. Looking at the equation for kinetic energy (KE = (½) mv^2), you can see that the more velocity produced during the gymnast’s initial run, the more kinetic energy she will have for the rest of the vault. Once the gymnast is at the top of her skill, for example, a handstand position at the top of…

Physics is everywhere. Especially in NASCAR which stands for National Association for Stock Car Auto Racing is a racing sport which the racing cars have motion. “NASCAR is motorsport's preeminent stock-car racing organization. The three largest racing-series sanctioned by this company are the Sprint Cup Series, the Xfinity Series, and the Camping World Truck Series.”(Mukul Bhatia.What is NASCAR?.www.quora.com.) On the rough racetrack nascar cars are made to be driven in extreme conditions. In…

Ava Lilienthal Science Barcus 7-4 The Physics Behind Soccer Soccer really has a lot to do with science. From Newton’s laws of motion to the momentum of the person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest…

Kinetic Energy and Potential Energy Math Exploration 2/14/2018 Part 1: Finding Kinetic and Potential Energy Directions: For each situation, you need to determine if the object has KE or GPE or both. Then find their values. Be sure to include the correct units. 1. A 2-kg bowling ball sits on top of a building that is 40 meters tall. Circle one: KE / GPE / both Show your work for finding the values of each type of energy the object has: The ball is not moving and is at a height above…

Fill the flat beaker with water. 6. Place a plastic bag over the top of the cylinder and place it, upside down, in the flat beaker. Make sure the bottom of the beaker is always underwater. 7. Fasten the beaker in place using the stand, clamp and boss. 8. Place one end of the tube inside the large beaker and fasten the other to the cynical flask’s arm. 9. Quickly pour the CaCO3 into the cynical flask, plug in the rubber stopper and start the stop watch. 10. Every 10 seconds,…

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 energy to be turned into…

The purpose of this experiment was to understand kinetic and potential energy and verify the Law of Conservation of Energy. Kinetic and potential energy are both forms of energy that usually coincide with each other; potential energy usually changes into kinetic energy and vice versa. While potential energy results from an object’s position or arrangement of parts, kinetic energy results from an object’s motion. Together, the sum of an object’s kinetic energy and the potential energy at that…
