Simple harmonic motion is closely related to a uniform circular motion. A real life simple harmonic motion. Review Question 1 Answer the following questions as you watch the first YouTube video(Simple…

Angular Displacement The angle which an object moves around a circle is called the angular displacement. This angle is usually expressed in radians. Hence, there are radians in one complete…

How does a capacitor work? When a capacitor is connected across a power source, it starts charging up as current flows in the circuit. Initially when the capacitor has…

What is a capacitor? A capacitor is an electrical component that stores charge. It is usually made by having two parallel plates thinly separated by an insulating material. This…

Why does a orbiting satellite not fall to the Earth? A common misconception among students is that orbiting satellites do not experience gravity. It is argued that since these satellites…

Gravitational Potential and Potential Energy Gravitational potential at a point is the amount of work needed to bring a unit mass from infinity to that point. Gravitational potential is defined…

Concept of a Gravitational Field and Force A gravitational field is a region in which a mass experiences a force. A mass, that is present inside a gravitational field experiences…

Capacitor is an electrical component that stores charge. As charges are stored, potential energy in the capacitor also increases. In this post, I would like to explain how to calculate…

The table provides the data for the acoustic impedance and absorption coefficients for muscle and bone. A parallel beam of ultrasound of intensity enters the muscle of thickness 3.0 cm…
