Kinetic energy

My testable question is an off the ground spike more powerful and faster than a spike that is done on the ground. I will answer this by spiking the volleyball ten times, five times in the air and five times from the ground. I will be ten feet away from the wall and I am going to measure how high it bounces after it touches the ground. I chose this topic because I love volleyball and I wanted to know which position has more force and power. My hypothesis is “If an off the ground spike is made,…

and Photographs Division. Once everyone's onboard, the cars are released and start to roll down. When they round the brow of the first hill, the force of gravity makes them hurtle energy as well. Even the rattling noise the rollercoaster makes uses up some of its energy. The cars lose more and more of their original energy the longer the ride continues, and, since the cars have no engines, there's no way of replacing it. That's why the loops on a rollercoaster ride always get smaller and…

water gas shift reaction and steam reforming reaction. The total Gibbs free energy of a system is a function of Gibbs free energy of each of the components. For minimizing the Gibbs free energy, the mass of each individual element present in the gaseous mixture is considered. The amount of an element in the resulting gas mixture produced must be equal to its amount obtained from the ultimate analysis of the…

Model descriptions SWAN model The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the…

II. 2. Hydraulic Jump 2.2.1. purpose 1. to create/generate hydraulic jump 2. To clarify questions about the fluid flow. 3. To determine the slatrility and characteristics of hydraulic jump, performed in the laboratory using impulse momentum and energy equations are specific. 4. to compare between the depth of flow measurements and the results of the theory. 2.2.2. Basic Theory A hydraulic jump occurs when the flow of the flow at a high speed exposure at a low-speed flow that occurs at the…

angle was for of each hill. The more pointy the hills, the more dangerous the landing of the cart would be. Another example would be the height of the loop of the roller coaster. The loop should be high enough so that the cart could travel with more energy. 2. Describe a roller coaster design that the cart was able to travel through safely. A roller coaster has to be able to nice and smooth without stopping to abruptly. Another way a roller coaster design that would move the cart safely…

The search for "energy capsule" made me get acquainted with such a mysterious phenomenon of nature, Ball lightning. In truth, no one yet knows exactly drive it or not. But I'm with some degree of risk still decided to consider a Ball lightning energy accumulator. Here is a brief those characteristics of ball lightning, which are made by scientists on the basis of a large number of eyewitnesses: the energy contained in the lightning - from 0.1 to 4 kWh; lifetime - from several seconds to minutes;…

recycling cans means that new aluminum cans will have to be made, and to make new aluminum cans people have to dig into the earth’s crust which wastes a lot of energy and emits more greenhouse gases which helps in global warming. Recycling an aluminum can saves enough energy to power a television set for 3 hours. This is a huge amount of energy preserved. This shows that what we are doing is important because…

processes in industry. You must understand the terms related to temperature measurement. Temperature Temperature is a measure of the average kinetic energy of the particles in an object; kinetic energy is the rate at which molecules or particles move. When particles of any matter (solids, liquids, gases or elementary plasmas) move faster, they carry more kinetic energy and feel warmer than a material with slower particles. Boiling Boiling is the process where molecules transition from the liquid…

planet is done by using energy? In fact, you are using energy right now. Energy is the capability of producing work. Energy makes a change in an object. Force plays a role in deciding whether an object has done work or not (“Work and energy”, 2015). If the object moves towards the direction of the force, the work done is positive (“Work and energy”, 2015). If the object moves away from the force, the work being done is negative (“Work and energy”, 2015). An important aspect of energy is that it…
