Fundamental physics concepts

observe and record the visible emission spectra of hydrogen and other samples to determine certain properties of these spectra. In this experiment recorded the spectra of several element samples and found several properties of these spectra using fundamental equations in spectroscopy. I calculated with some degree of certainty the orbital levels from which the electrons moved in hydrogen and came to conclusions about the changes in energy of other…

multitude of factors. To understand these factors, mathematics can show us how they interact and how they affect performance. Water Bottle Rockets are mainly used for educational purposes in schools. They are used to explore basic aerodynamics and physics. Water rockets demonstrate many different forces such as weight, thrust, lift, and drag. Basic parts of a common bottle rocket include a nose cone, fins, a base, and a launcher used to launch the rocket. Rocket propulsion started…

Is it possible for a star to burn cold? The answer is not as simple as you may think; while all sars burn hot, there are some cold enough to touch (if you survive the vacuum of space). In 2011, NASA’s satellite WISE discovered six Y-Dwarf stars burning as cold as ice, not even forty light years away from our own sun. This type of star is often referred to as a Brown Dwarf, or a failed star. There are three types of Brown Dwarfs; L-Dwarf, T-Dwarf, and Y-Dwarf, the Y-Dwarf being the coldest.…

this basis Bradt established five ‘badges of honour’ which can be identified as the pillars of backpacking (as citied in Welk, 2004, p.80): 1. To travel on a low budget 2. To meet different people 3. To be free, independent and open-minded 4. To organise one’s journey individually and independently 5. To travel as long as possible 2.1.2 Backpacker profile Furthermore, this group characteristic is overlapping with other segments and should not be considered as a homogenous group due to different…

The objective of the lab is to find the calorimeter we used by determining the heat given off from pringles and calculate how much energy was released by the burning food substance. In addition, we can also use the concept of conservation of energy that energy cannot be created or destroyed. Introduction In order to complete the snack energy lab, calorie and calorimetry will be use as a major technique. By burning pieces of food, the chemical energy stored in molecular bonds is released as heat…

The molecule butane was observed while its dihedral angle was changed in 60 degree increments from 0 degrees to 360. The dihedral angle that had the largest potential energy was at 0˚ and 360˚. This is because the molecule was in an eclipsed conformation, an orientation of the molecule that causes there to be a lot of potential energy because the two largest molecules are fighting space, making it unstable. The lowest potential energy and most stable conformation was seen at 180˚which is…

their changes. At this juncture I introduce the reader to some more concepts related to the physical aspects of Universe which have been relatively compared and standardized by the human beings on the basis of basic laws by giving it definite name. Space: Space is the boundless, three-dimensional extent of universe in which objects and events occur and have relative position and direction. This is considered to be of fundamental importance to an understanding of the physical universe. Time:…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

frictionless; but it travelling the flat part, the object loses 688 mJ of mechanical energy, due to friction. The object is released at point A, which is height h= 1.05 m above the flat part of the track. Where does the object finally come to rest? Concept: The potential energy U is defined as: U=mgh Here, m is the mass of the body, g is the free fall acceleration and h is the fall of height. Solution: To find the potential energy of the object at the point A, substitute 234g for mass of the…

For task one My hypothesis was "If the forces on each side of the rope are equal, then the sum of forces will be zero. If we can determine the force each person on both sides of the rope, then we can determine if the sum of their forces will equal zero. " which was, correct. I know my hypothesis was correct because of the balanced force. A balanced force is when you have an equal amount of force on each side of an object when force is being exerted on it, it doesn't move because there is no…
