How Does The Height Of A Ramp Affect The Distance Of A Toy Car
I will carry out an experiment to answer this question.I will do this by making a ramp with an adjustable height and rolling a toy car down it to see how long it travels before it stops. I will then work out the work done by using this equation -Force (n) x distance (m) = work done (mgh)I predict that the greater the slope of the ramp the longer the model will take to stop.This will happen because the higher…...

Heat Engine Lab Report
Heat engine lab Intro: when an engine runs, it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be…...

Graphical Analysis Of Motion Examples
Equations are great tools to describe a particular phenomenon or situation, but at times, they would not just suffice. We need visualization to further understand what is happening – a mathematical picture called a graph. More than just a visual representation of the relations between certain quantities plotted with reference to a set of axes, graphs give us a complete description of various actual events. A common example of graphs is graphs of motion. Motion graphs come in different forms,…...

Essay Example on Hydrogen Spectrum
The following sample essay on Essay Example on Hydrogen Spectrum. A hydrogen discharge tube is a device that can trap small amount hydrogen in a sealed tube of glass, and if potential difference is applied to that tube an emission of an atomic spectrum can be produced. The emission of the spectrum is produced from the excitation of the hydrogen electron (by the voltage) to a higher energy level and falling back to its original one. In this practical a…...

Conductivity Lab Report
When an ionic compound forms, the anion transfers an electron to the action which creates an electrostatic bond and an electrically neutral compound. Also, they readily solve in aqueous solutions and are good conductors of heat and electricity. Further, ionic compounds can be classified as either strong conductors or weak conductors. In contrast, molecular compounds are formed from non-metals. Molecular compounds share electrons between atoms forming a covalent bond.Essay Example on Electrical Conductivity Lab In general, molecular compounds do not…...

Voltaic Cell Experiment Lab Report
Voltaic cell is a device in which a redo reaction spontaneously occurs and produces an electric current. In order for the transfer of electrons in a redo reaction to produce an electric current and be useful, the electrons are made to pass through an external electrically conducting wire instead of being directly transferred between the oxidation and reducing agents. A salt bridge must be used to avoid popularization of the electrodes by facilitating the circulation of ions from electrolyte. Each…...

Solubility Of Potassium Nitrate Lab Report
The relationship is nonlinear, which means it isn’t form a straight line when plotted on a graph. Now, there are three main factors, which affect solubility (besides pressure). Temperature will affect solubility. If the solution process absorbs energy then the solubility will be increased as the temperature is increased. If the solution process releases energy then the solubility will decreased with increasing temperature. Molecular size will affect the solubility. The larger the molecule or the higher its molecular weight the…...

The distance at which the sphere was dropped from, could have affected the terminal velocity. By doing a reverse engineering calculation using the equation given in the lab sheet for Castro oil (0. 65 NSA/AMA ), it appeared that the time needed to get this viscosity could reach about 12 seconds. This was quite impossible in our experiment to be obtained. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be…...

Wheel And Axle Lab Report
Now for a rolling wheel the kinetic energy has two monuments, translational due to the bodily movement of the mass centre down the slope and rotational due to the wheel spin. Now the source of this energy is the loss in potential energy as the wheel moves down the slope. If it is reasonable to assume that friction effects are insignificant then no energy is lost. Thus the loss in potential energy becomes a gain in kinetic energy.Essay Example on…...

Assuming that pressure does not change, if you double the absolute temperature of a gas it causes the volume of that gas to double. Temperature and volume are proportional. The volume of a gas increases by 1/273 of its volume at CO for every degree Celsius that the temperature increases. This relationship happens because while the gas molecules are moving around in their container in different directions and peed, they will have an average amount of energy that is the…...

Another example Is that you cannot hold anything; everything you try to hold will slip off your…...
