Kinetic theory

Acceleration, velocity, and gravity are important concepts that each played a role in this lab. Velocity is defined as the speed and direction of motion of a given object. The equation for this particular concept is: v=d/t which states that velocity equals displacement in respect to time. Acceleration is defined as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity,…

Rube Goldberg Project For this Rube Goldberg project I am going to explain how my machine worked. My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and…

In the first experiment, the acceleration of a falling mini-basketball, the results gathered disagreed with my predicted outcome. Originally, I could not imagine how the graph might appear. I could not visualize an object falling and what its acceleration, position, and velocity might be on the graph. However, after completing the first experiment, I realized that the graphs would look somewhat the same in relation to the basketball since this object was not affected as much as the lighter…

Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…

greater fraction of molecules will be above that energy and will therefore be able to react successfully. Therefore, more collisions have sufficient energy for reaction to occur. Consequently, the reaction rate increases. Relative to the Collision Theory, as more molecules are bouncing into each other, more collisions in a system occur,. This grants a higher probability that the molecules will complete the reaction. The reaction will then happen faster(rate of that reaction will…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

1. Iodide proved to be the more reactive nucleophile in this reaction. This nucleophile was faster than Chloride, because on the periodic table, Iodine has a bigger atomic size, while Chlorine has the higher electronegativity, but size trumps electronegativity, as according to ARIO rules. This means that Iodine is more acidic than Chlorine, which means that in the reaction, the Iodide could displace the Bromine from the 1-bromooctane, because it has a bigger size, much faster than the Chloride,…

Welcome to the Loop-Dy-Loop!!! This roller coaster is found in the beautiful area of Hersheypark inside the water park. The roller coaster, is filled with many twists, turns, and loops. This roller coaster is not just any roller coaster, it has a fabulous view of the whole park. The tallest point on this ride, where you feel the highest potential energy, is over 4,586 feet tall. This ride is over four football fields long!! While you are waiting in line you can see that the cars have three rows…

Roller coasters with loop-the-loops are generally rides that appeal to thrill seekers, however without the use of dynamics, these rides would not be able to function. A roller coaster loop-the-loop is a type of large scale centrifuge, as one approaches the loop, the rider's inertial velocity is straight ahead. However the track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…
