Non-uniform motion is the type of motion where an object has varying speed in a trajectory with respect to a reference point. This type of motion is a complex motion as the motion becomes unpredictable. Various external forces like friction, … Read more

The equations of motion are mathematical concepts used to predict and analyze motion. Motion is a part of daily life. So, to analyze motion, physicists have developed certain mathematical relationships. They are the fundamental concepts of physics. The same equations … Read more

Physical quantities are divided into two types: scalars and vectors. On the basis of certain categories, the physical quantities are divided into these two types. The quantities like mass, distance, speed, displacement, force, etc., are described and measured accordingly. Scalars … Read more

Errors and uncertainty are the two basic outcomes of any measurement carried out. Almost every scientific measurement and experiment involves measuring physical quantities such as length, mass, time, temperature, current, voltage, force, or volume. However, no physical measurement can give … Read more

What Are SI Units? SI Units are an important part of the measurement of physical quantities. Measurement is the foundation of physics. So, to make the measurement system easily understood by everyone, a common standard system was built, called the … Read more

Physical quantities are the language of physics to describe measurable quantities. Physics always deals with measurements and interactions, and these must be accurate and precise. So, to give a meaningful measurement, the results are expressed in numerical values and units. … Read more

Introduction and Definition of Solar Water Heater A solar water heater is a heating device based on solar energy. In the past, we used fire from wood or gas stoves to boil water. After the development of technology, induction and … Read more

Introduction and Definition of Solar Cooker A solar cooker is a cooking appliance that is based on solar energy. We generally cook food using gas, stoves, induction, etc. Moving further back, we were dependent on firewood, coal, kerosene, etc. Unlike … Read more

Introduction and Definition of Photovoltaic Cell Photovoltaic cells (PV cells) are modern devices that directly convert sunlight into electricity. They are also called solar cells. Solar panels are the most popular applications of photovoltaic cells. The word “photovoltaic” is composed … Read more
