Answers 1. Kinetic energy is the energy possessed by a body due to its motion. Potential energy is the energy possessed by a body due to its position or state. Kinetic energy can be transferred from one object to another, in case of collisions. Potential energy cannot be transferred. Thus, the potential energy is stored in the object due to its position, whereas the kinetic energy is possessed by an object due to motion. Eg: A ball kept on the edge of the table possesses potential energy due to its
Energy is a property of matter which can be transferred to other matters or transformed into different forms, although it cannot be created or destroyed. A common definition of energy is that it is the ability to do work. Work is the transfer of energy. Work is done on an object when energy is transferred to that object. If one object transfers energy to another object then the first object does work on the second object. Work is when a force is applied over a distance. To calculate work, find the
have energy, without energy you have nothing.” Potential and kinetic energy have many similarities as well as differences between each other. For example, a similarity that they both have is that they can both be converted into other forms of energy. An example of a difference between potential and kinetic energy is potential energy is energy that is stored meanwhile kinetic energy is energy that is in motion. One of the most important similarities between potential energy and kinetic energy is that
In Chapter 14 (Kinetics of a Particle: Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body: Work and Energy), both apply a same concept. It is concept of work and energy to solve the problem. Chapter 14 use the concepts of work and energy to analyze motion of a particle, while Chapter 18 apply work and energy methods to solve planar motion problems. In both chapter, problems that involve force, velocity, and displacement can be solve by using the resulting equation. Chapter 14 states
Title : The similarities and differences of Chapter 14 (Kinetics of a Particle : Work and Energy) and Chapter 18 (Planar Kinetic of a Rigid Body : Work and Energy) The similarities 14 and 18 In chapter 14, we will analyse motion of a particle using the concepts of work and energy. The resulting equation will be useful for solving problems that involve force, velocity, and displacement. Before we do this, we must first define the work of a force. Force, F will do work on a particle only when the
direction. These elastic collisions are when the total momentum and kinetic energy are conserved, and there is no loss of momentum or kinetic The vast majority of rollercoaster start with a steep motorized climb in elevation or gain in potential energy. Once at the top, the roller coaster has enough potential energy to make it back to the loading station. The roller coaster uses its stored potential energy and converts it into kinetic energy to carry the car throughout the track. Further examining the wheels
The Effect of a Falling Object's Weight On Its The Terminal Velocity There are a number of factors that effect terminal velocity, such as surface area, weight of object, height from which it is dropped, and wind. I have chosen to investigate the weight of the object. It will be the only variable that I change. AIM: The aim of this investigation is to find out what happens to the terminal velocity when the mass and weight of the falling paper case is changed. PREDICTION: I predict
chucking the chuck will be spinning around the spindle and an attachment will be used that will act as a catcher that will be on the outer radius of the chuck. We will also be able to calculate the velocity of the wood leaving the chuck and the kinetic energy. Lathes & Chucks A LATHE is "a machine tool designed primarily to do turning, facing, and boring. Their versatility permits multiple operations to be done with a single setup of the workpiece. Consequently, the lathe is the most common
it would have a boiling point of -75øC and a freezing point of -125øC4. This would mean that, on Earth, water would be a gas all of the time and life would not be possible. When heat is applied to solid water, some hydrogen bonds get so much kinetic energy that they break and the ice melts. Liquid water does not necessarily have all four hydrogen bonds present at all times but it must retain some of them. All plant life on Earth benefits from the ability of water to make a hydrogen bond with another
the wind to produce energy. This is what wind turbines do and now I will be researching them to determine the physics involved with them and how they work, their history, along with some statistics from the United States. Then I will go in-depth for the wind turbines of Texas, Washington, and Kansas and compare them. The Physics of Wind Turbines There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on
"Using the definition (which is taken from a formula in rotational energy) I=?ri2?mi and take the sum as ?m?0 (where I is the moment of inertia and ri is the perpendicular distance of the infinitely small mass' distance from the axis of rotation). In this limit the sum becomes an integral over the whole object:I = lim ?ri2?mi = ? r2 dm.

When you strike a bat against a ball it sends vibrations, much like the vibrations acting on airplanes or bridges, which travel in waves through the bat. This motion is important to understand because every vibration the bat experiences takes energy away from the ball's speed as it leaves the bat. If you hit the ball at a bat's "nodes", the frequencies (each bat vibrates at several low and high frequencies at once, which is like the harmonics of stringed instruments) cancel out and since this
maintain the efficiency of induction motors speed control is required. Variable frequency drives (VFDs) are suitable for this purpose. 1.2 Optimize Power Usage Centrifugal loads offer the greatest potential for energy savings by using variable frequency drives (VFDs) to control speed. Energy consumption in a centrifugal fan and pump applications follow the affinity laws. Affinity laws determined that the flow is proportional to speed, pressure is proportional to the square of speed, and horsepower
20 miles per hour to reach the top of a 30 foot hill. Then you reach the top where you are going to have the most potential energy, suddenly you drop 25 feet and you are going 65 miles per hour when you will be at the terminal velocity. Out of nowhere you go into a loop at 65 miles per hour and you see the loop and it is huge.It is almost like you can feel the kinetic energy rushing through you. When you enter the loop you start to turn ever so slightly and then in the distance you see loop number
with my first definition. It is hard to tell just what kind of cool someone is talking about. Also, my first definition – a desirable image that excites the mind – somewhat has to do with energy, but it is not low in energy like all the other meanings of cool. If it is exciting the mind, it is raising the energy and then cannot be truly thought of as cool. This is probably why my first definition is not in the OED. Cool is a word that can be used as an adjective, verb, and even a subject (when
increase the energy in the form of kinetic energy which they possess. Because the enzymes and substrate molecules are moving faster the chance of them colliding in a certain time and area is increased. Thus the chance of the hydrogen peroxide molecules binding with the Catalase molecules active site and reacting is higher. However after a certain point increasing the temperature will begin to hinder the activity of the potato catalase. The reason for this is that the energy being supplied
same number of electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons
The Physics of an Electric Motor An electric motor is a device used to convert electric energy into rotational kinetic energy. There are two different types of electric motors, and each has there own use. The different types are direct current and alternating current motors. Each of these motors will be analyzed in the following. To understand how this motor works, we must understand the relationship between electricity, and magnetism or simply put electromagnetism. Direct electric current
the potato cylinder. We will measure the mass of a potato cylinder after a certain amount of time in a certain solution. Fair test: To keep the test fair we need to keep the controls the same. Like keeping the temperature the same so the kinetic energy doesn't cause a faster reaction. Prediction: I think that if the solution is more concentrated with sugar then the mass should go down. I think this because the concentration is made even inside and outside of the potato so water has
out how the temperature affects the rate of reaction. Hypothesis: I believe that the higher the temperature, the faster the reaction the reaction between the sodium thiosulphate and hydrochloric acid. This will happen because kinetic energy and the heat energy makes the particles move faster, collide faster and react faster; therefore they can break bonds easier. Scientific Knowledge: Firstly, I will explain the equation needed to follow out the experiment: [IMAGE]Na2 S2O 3(aq)
