There are four laws of thermodynamics – zeroth law, first law, second law and third law. First law of thermodynamics has been explained in another article. Second law of thermodynamics has three different statements – Kelvin-Planck’s statement, Clausius statement and the statement in terms of entropy of universe. In this article, we are going to … Read more
You might have noticed that when you stretch a rubber, it tries to come back to its initial condition. Did you ever think why is the rubber trying to do so? If you don’t know the cause of such activity of rubber, let me tell you that this is caused by a property of the … Read more
There are seven types of electromagnetic waves in the electromagnetic spectrum of light. Radio wave is one of those which is very impotant in different practical aspects. In this article, we’re going to learn all characteristics of radio waves including their wavelength, color and uses. This article answers the following questions – What are Radio … Read more
Suppose you need to measure the length of a notebook. Which instrument will you use? If you are not going to be scientific, you will measure it with a ruler scale. That’s fine because you don’t have to consider the error in that case. But if you are asked to measure the thickness of a … Read more
If a body has an unequal number of protons and electrons then we call it a charged body. It can have either positive charges or negative charges. Both type of charge can produce an electric field around it. The amount of charges and the shape of the body determine the type and value of the … Read more
We all use Batteries in our daily life as the source of electricty. Mobiles, Laptops, wall clocks and some other devices need batteries for their function. In recent times, Electric cars gained popularity that also use batteries as a source of electricity. You might have heard the term Cell in electricity as well. What is … Read more
In another article, I’ve discussed the Potential energy of an object. It’s the ability to do work due to its position at a height above the ground. In this article, I’m going to explain what is gravitational potential energy and what are some examples of it. What is Gravitational Potential Energy? The work done in … Read more
Electricity is one of the most essential things in our daily life. To deal with an electrical circuit, we need to know the physical quantities associated with it. Current, Voltage, resistance, power, etc. are among those quantities. Many scientists have given various laws of electricity and explained how to determine such physical quantities in a … Read more
The acceleration of a moving object depends on the net force acting on it. Therefore, the net force is an important quantity to study the dynamics of an object. There are different types of Forces depending upon their origin and nature. In this article, I’m going to explain friction and frictional force with definition, unit, … Read more
We cannot get any energy directly unless it is the light energy of the Sun. Luckily, we have enough mechanisms that can transform light energy into other forms like heat, electricity, chemical energy, etc. These energies can also be transformed among themselves. In this article, I’m going to explain different types of transformation of energy … Read more
