The acceleration of a ball down various inclines

In this experiment, I constructed a project to test the change in velocity of a spherical object down a slope, and how that is affected by different inclines. I will record the time a ball takes to get to the bottom of a plank, measuring the times it takes to get to different intervals. The… View Article

Gravitational energy

This is the gravitational energy lost by the jumper and when plotted, this graph should be linear. I could plot these on the same axis the point where the two graphs intersect is the extension at which the jumper comes to rest. Unfortunately my Eel-extension graph did not turn out as expected in a nice… View Article

Objective Morality

My purpose in writing this is to argue for the existence of an objective morality based entirely on rational and scientific reasoning. By “objective morality” I do not simply mean that morality exists in the sense that various societies consider various actions to be immoral. What I mean is that certain actions are inherently right… View Article

Dark Matter, Dark Energy

It is the intent of this paper to introduce the relatively recent theories of dark matter and dark energy and their relation to each other. These theories explain the observed increase in expansion rate of the Universe as well as explain why galaxies remain intact despite the apparent lack of sufficient mass to affect the… View Article

Life Without Gravity

In a world without gravity, one would be weightless, but always nauseous. Because of this, it would be very difficult to complete a lot of your daily activities without throwing up. If you tried to eat something while you and your food are floating around, you will probably have a lot of trouble trying to… View Article

Investigating circular motion

By plotting the graphs it can be observed the y axis is equal to v” and the x axis is given as r (radius), the gradient is given by (y2 – y1) / (x2 – x1). By working out the gradients it can be seen that the gradient for 50-gram masses is approximately 26, whilst… View Article

How gravity works

“Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is the attraction that exists between all objects”. (NASA gravity 2000) Gravity is a very essential part of life on earth. We are in the… View Article

The Ordered Universe Assignment

1. Why was the Ptolemaic system accepted as an explanation of celestial motion for over a thousand years? What did it explain? What system challenged the idea that Earth was the center of the universe? The Ptolemaic system says that the Earth is the center of the universe. Everything else surrounded the Earth. The Copernican… View Article
