1. Describe a roller coaster design that the cart was not able to travel through safely. There was only a few things that would make a roller coaster design dangerous for the cart. One example would be how pointy 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…

system. In doing this we were able to determine the velocity of the cart as a function of its height upon the roller coaster, find the kinetic and potential energy for each trial of the cart and conclude energy loss due to friction. The results from part one concluded that as the roller coaster cart went down a hill the potential energy was converted into kinetic energy that resulted in an increase of speed. When the cart was at its highest peak it had the lowest velocity, but at its lowest…

car is a car powered by a mousetrap. It utilizes potential energy, kinetic energy, and mechanical energy. Potential energy is a type of energy an object has because of its position. For example, elastic potential energy of a rubber band depends on how far it is pulled back from rest. The farther it is pulled back, the higher its potential energy. Once the rubber band is let go, the potential energy is then converted into kinetic energy, the energy of movement. The held end of the rubber band…

this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with the equation for kinetic energy. The equation, d_y=v_i t+1/2 at², was used to…

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;…

By using the pseudo first-order kinetics method, you are able to determine the rate law for the reaction between crystal violet and hydroxide ion. crystal violet hydroxide CV+ + OH- ————> CVOH Rate=k[CV+]m [OH-]n The objective for this experiment was to analyze the absorbance of the dyed molecule crystal violet using a colorimeter and the molar absorbance of the reactant. This data was used to calculate the concentration of…

In this model no any chemical reaction is considered.(Barba et al.) modelled gasification by considering it to occur in two steps, in the first of which the biomass is decomposed at high temperature to give primary gas and carbonaceous residue and in the second there is modification…

They are responsible for physical properties of compounds such as crystal structures, melting points, boiling points, vaporization, viscosity and surface tension, but not the chemical behavior of the three states of matter; when a molecular substance changes states, the atoms within the molecule are unchanged. These properties can therefore be used in identifying an unknown sample by comparing for example its observed melting…

Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface…

In Chemistry 2017-2018 I learned many things that can help out in daily life to keep others safe and to improve things. One thing that can be useful is knowing basic chemicals and elements to be safe and know what is inside things you have in everyday life. Knowing chemicals is good to know not to mix certain things that can possibly be dangerous or hazardous to your-self or others. Knowing not to mix ammonia and bleach is good because when mixed causes an toxic gas that can harm you, others,…
