Principle of Conservation of Momentum Video Tutorial
When a body is not moving, we understand that it is in static equilibrium. The resultant force acting on the body and the resultant torque about any point would be zero. Conversely, if the resultant force acting on the body is not zero, the body will changes its state of motion, or we say the body accelerates according to Newton’s laws. In this chapter, we will analyse how forces acting on a body will cause it to accelerate. We will also explore the case when masses collide with each other and learn more about the Principle of Conservation of Momentum.
Simple Harmonic Motion Video Tutorial
Before we go into the study of wave and its interference, it’s imperative that we understand the basic of a periodic motion, in particular the simple harmonic motion (SHM). In this chapter, we will be exploring the kinematics and energy of a simple harmonic motion. In the later part of this chapter, we will introduce damped oscillation where energy is lost from the oscillating system and also the forced oscillation where energy is added to the oscillating system by an external driving force. An important application to this is the phenomenon of resonance.
Electromagnetism Video Tutorial Part 1
In the fifth century B.C., the Greeks already knew that there are some rocks that attract bits of iron.
And they are very plentiful in the district of Magnesia, and so that's where the name "magnet" and "magnetism" comes from.
In eleven hundred A.D., the Chinese used these needles of magnetite to make compasses, and in the thirteenth century, it was discovered that magnetites have two places of maximum attraction, which we call poles.
So if you take one piece of magnetite, it always has two poles.
Let's call one pole A, and the other B. A and A repel each other, B and B repel each other, but A and B attract each other.
Electromagnetic Induction Video Tutorial 1 - Faraday's Law
Faraday’s Law states that the magnitude of the induced EMF is directly proportional to the rate of change of magnetic flux linkage with the coil. This is a simple experiment that demonstrates the law.
Electromagnetic Induction Video Tutorial 2 - Lenz's Law
Lenz’s law states that the direction of the induced current is such that its magnitude will always opposes the flux change that causes it. This is a simple experiment that demonstrates Lenz’s Law.
Electromagnetic Induction Video Tutorial 3 - Application of Induction
An important application of electromagnetic induction is the microphone. The Microphone is defined as an electric transducer or sensor that converts sound into an electrical signal. Microphones are used in many applications. They are used in various instruments like telephones, tape recorders, hearing aids, motion picture production, live and recorded audio engineering, in radio and television broadcasting and in computers for recording voice, and also for non acoustic purposes such as ultrasonic checking. Loudspeakers can also function as microphones when in reverse use.
The basic function of a wired microphone is to capture waves from various surfaces and convert them into an electrical signal. A common signal flow is activated with the help of thin membranes producing a proportional electrical signal.
Most microphones in use today for audio, use electromagnetic generation (dynamic microphones), capacitance change (condenser microphones) or piezoelectric generation to produce the signal from mechanical vibrations.
Alternating Current Video Tutorial
The life story and work of Nikola Tesla. He invented AC electricity, Neon Lights, Radio transmission and the Electric motor. After his demonstration of wireless communication in 1894 and after being the victor in the War of Current, he was widely respected as one of the greatest electrical engineers who worked in America. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance.
