Kinetic energy

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…

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…

In class today we dropped a racket ball beneath a sensor in order to describe the motion of the ball in free fall. We collected our data through a sensor that determines the distance of an object from its current location. The sensor connects to a LabQuest that connects to the program Logger Pro, which copies the data collected and forms a position versus time graph as well as a velocity versus time graph. In order to have the data fit the situation of the bouncing ball, we zeroed the sensor so…

collisions make changes (or are fruitful). Fruitful or effective collisions require enough energy to break pre existing bonds and form new ones. In order to have enough energy the particles they need to have the right orientation and enough force.…

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…

Experiment 3: Buoyancy Introduction Mass is described as the measure of the amount of matter contained in an object. On the other hand, weight is the measure of the force of gravity acting on the mass. Mass is measured in kilograms, while weight is measured in newtons. The density of an object is found by dividing the mass by the volume. Buoyancy is the upward force of a liquid which counters the weight of an immersed object. The theoretical buoyancy of an object can be calculated by using the…

Abstract The purpose of this experiment is to determine the relationship between the temperature and pressure of air at constant volume which placed the Jolly’s bulb in water of different temperature. At the constant volume of the air in the Jolly’s bulb, the temperature and pressure of the air are measured and recorded throughout the experiment. The result shows that the pressure of the air in the Jolly’s bulb increases as the temperature rises, and the pressure decreases as the temperature…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…

The Dropper is an extraordinary ride unlike any other. As the coaster winds rapidly through Sherbert Park it presents breathtaking scenery as riders travel over and through Willow River in Hudson, Wisconsin. This mid-north roller coaster, constructed of metal, has four cars per train, holding six people per car. One train will be on the track at a time. The ride was designed to appear like a torpedo, featuring a point on the front car, and black cars with burnt orange outlines, and red flames…

The egg drop project we did involved many physics principles. One of them was air resistance, which happened because the egg dropped and it accelerated, while the velocity increased. Then the resistance of the air to the egg box motion also increased, which means the upward force of air resistance balances the downward force of gravity, so the egg box dropped at a constant speed. We attached balloons to the box we made in order for the box to pass through the air while softly landing. We believe…
