Professor Patterson Hume and Professor Donald Ivey from the University of Toronto present this video about how things look different under different circumstances. They begin the video arguing about who is upside down, and because Dr. Hume is at the top of the screen (upside down), most people would assume...

Physicists are a special breed of people. They are fascinated with things that seem intangible. They create complex questions about things that are a hundred times smaller than just being microscopic. Theorists have ideas based on laws provided by historical physicists like Isaac Newton. Experimentalists create ways to test the...

Most people are unaware that they are obedient to three laws that seem to govern the entire universe. A brilliant man named Isaac Newton proposed these laws during a life consumed by scientific experimentation. He was always curious about everything under the sun. He wanted to know what caused objects...

A sound is a wave that moves through air. The disturbance itself is what moves, not the individual particles. The individual particles oscillate back and forth in place. Sound produces compressed air. The collision of air molecules against one another is what allows the sound wave to travel from one...

The lab conducted regarding “Rainbows and Blue Skies” resulted in the ability to see how both items are discovered, developed, and applied. Each of the two items have their own chemistry aligned with their formation. Rainbows are a spectrum of light caused by water droplets. The rainbow’s ability to form...

Introduction A bar magnet produces magnetic fields which are believed to follow prescribed magnetic lines. In the previous experiment, the application of the magnetic field in the operation of a transformer was observed. In the transformer, two coils which are electrically isolated develop a magnetic flux in the primary coil....

Light is the connection between humans and the universe. It is through life that we could experience distance, objects, colors, our world, communicate, support life and even look back to the beginning of existence. Light is the electromagnetic radiation detected by the human eyes, its interaction with the matter have...

Essence: The main objective of this laboratory experiment is to examine the resistance through a light bulb and through a variety of series and parallel combination of bulbs. Another objective of the bulbs experiment is the verification of Ohm’s law by analyzing the light and voltage through a bulb. Ohm’s...

Two-dimensional waves are waves that have the ability to travel in more than one dimension. Such waves are those that can travel around corners. Examples of two-dimensional waves are sound waves and water waves. Two-dimensional waves can be illustrated on a ripple tank, which is a glass-bottomed water tank. Dark...

Hydroelectric power is a clean source of renewable energy. This beneficial power source has been utilized in developed nations such as the US for many decades but its potential has not been fully realized in third-world countries. Due to its relatively low operating expense, local farm irrigation, flood prevention and...

Ohm law is attributed to a German physicist known as George Ohm who ascertained the relationship within any DC electrical circuit that exists between current, resistance, and voltage. In electrical engineering, the relationship in Ohm’s law states that, the potential difference in any ideal conductor must be proportional to the...

Ohm’s law was developed in 1827 stating that “the current flowing through a conductor is directly proportional to the potential difference across its ends” (Sardar 90). In other words, the current that flows through a conductor at constant temperature is directly proportional to the potential difference across the ends of...

Theory In order to achieve static equilibrium, various conditions have to be met. Among these conditions are the resultant force and its angle of application. Therefore this experiment intends to examine and investigate these factors and conditions necessary for the static equilibrium. According to Newton’s first law, the static equilibrium...
