Kinetic energy

order to complete its simple task, which was to turn on a Roomba. One of the most prominent physics concepts within our project was gravity and/or gravitational potential energy, which could be seen in places such as the inclined planes and the hammer swinging down. Gravity was the downward-pulling force that allowed the energy to be transferred from the top level, to the Roomba on the floor. The toppling rule was another major concept in our project, as it was integral for the dominoes and the…

Trayc Poppenhager May 5, 2015 TA: GK Chem 341 Thermodynamics and Kinetic Control Goal: The overall goal of this experiment was to learn and observe about kinetic and thermodynamic control of different reactions by noticing which product forms faster or slower and possibly which reaction is more stable than the rest of the reactions. Significance: Organic chemists find using kinetic and thermodynamic control useful because they use the concept of the reactions to figure out…

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 instant is its total mechanical energy,…

You, reading this paper, have you ever wanted to learn about the physics of rollercoasters? This research will explain how potential energy is converted into kinetic energy throughout the roller coaster. Two variations of roller coasters will be built. The roller coasters will be used to compare how the marble’s energy is affected by the hills, turns or loops of each roller coaster. Now let’s test their potential. The concept of a roller coaster can be dated back as far as the 1400’s.…

Research Question How does the change in hydrochloric acid concentration affect the rate of reaction between sodium thiosulfate (Na2S2O3(aq)) and hydrochloric acid (HCL(aq))? Background to the Research question Collision Theory Back in 1916, scientists William Lewis and Max Trautz proposed the collision theory, which qualitatively explains how chemical reactions take place and why reaction rates change for various reactions. Chemical reactions involve collisions amongst reactant particles or…

Chemical kinetics are governed by the mathematics of systems of differential equations (Thermodynamics and Kinetics). This means that the rate of any chemical reaction is determined by the type, and amount, of reactants present. Note the rate of a reaction is how fast it occurs. Furthermore, such rate equations can either be distinctively linear or non-linear when graphed. Non-linear equations are supposedly more complex as they generally react to small changes within its parameters…

hChemical kinetics deals with the rates of chemical processes. Any chemical process is considered to consist of number of one or more single-step step which are known as elementary reactions elementary processes or elementary steps. Elementary reactions may involve dissociation or isomerisation of a single reactant molecule, which is referred as unimolecular step. Also there may be a single collision between two molecules, which is referred as a bimolecular step. It should be noted that…

To enable them to react we can either change the shape of the curve or move the activation energy (explain later on keep reading). One of which is to increase the temperature of the reaction. As temperature increases the rate of reaction increases. This is because the particles becomes more energetic causing them to have more kinetic energy as a result they move faster and more collisions occur with the required Ea (collision frequency increases). Using this knowledge…

of conservation of energy, friction, centripetal force, and normal force, just to name a few. Gravity, the law of conservation of energy, and friction all play major roles in the functionality of roller coasters. A roller coaster ride typically begins with an ascent, powered by a motor, to the top of a high hill. From this point on, the ride is powered simply by gravity. At the top of the first hill, the roller coaster car possesses a lot of stored, gravitational potential energy, which…
