Potential Energy of Gravity One situation in which there is a potential for work to be done is when an object is elevated a certain distance above the Earth. When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy. Kinetic molecular theory (also known as particle theory) states that all matter is made up particles and these particles are always in motion. If two vehicles moving at the same speed are involved in a collision, the vehicle that weighs less will take the greater impact. Kinetic molecular theory is useful in describing the properties of solids, liquids and gases at the molecular level. Example Problem 4. We know that rotational kinetic energy is written as, KE = 1 2Iω2. h = K f - K i = K f. and its velocity at that point is. To compute for the kinetic energy, two essential parameters are needed and these parameters are mass (m) and velocity (v). The principle is described by the physicist Albert Einstein's famous formula: =.. The most efficient large-scale storage system in operation. For the car going from 40 mph to 60 mph, the KE = 1/2*m*602 – 1/2*m*402; so KE = 1,800 m – 800 m, or 1000 m. Comparing the two results, we can see that it takes a KE of 1,000 m to go from 40 mph to 60 mph, whereas it only takes 200 m to go from 0 mph to 20 mph. Physics For Scientists and Engineers. Calculating kinetic energy If we know the mass of an object and its velocity we can determine the amount of kinetic energy. HYDROELECTRIC PUMPING. Kinetic energy is determined by calculating the speed velocity or mass of an object while it is moving. Here the work-energy theorem can be used because we have just calculated the net work, Wnet, and the initial kinetic energy, 1 2mv02. A Joule is a kilogram x meters/seconds What is the most efficient way to store energy? This is called the work / kinetic-energy theorem. It is important to realize that you are not simply working against speed, as the car’s kinetic energy will be four times as great as the speed at which it is traveling. Kinetic Energy (KE): energy in motion A great example of the difference between kinetic and potential energy is from the classic "snake-in-a-can" prank, shown in Figure 1. Report 8 years ago.
