Motion of objects under gravity

Have you wondered why an apple hits the ground when it falls from a tree but why the moon does not hit the earth? In this tutorial, we will look at different types of motion under gravity.

Principle of Air Conditioning

In this tutorial, we will look at how we can transfer heat from a low temperature region to a high temperature region.


indian unioun for pure and applied chemistry its a full form of IUPAC its a general name of organic compound.

How to determine the empirical and molecular formula of a compound

Difference Between Osmosis And Diffusion

This problem discusses the main differences between osmosis and diffusion, as they are both passive transport mechanisms but differ in terms of how these processes occur.


We are given mass in grams of a particular compound. We need to convert it into moles of that compound given the ratio formula and the masses of individual elements.

finding average speed

In situations where you are given different speeds and the average speed is required, you need to keep in mind that the average speed is by definition: total distance/time elapsed. People get this wrong all the time, trying to do s= (s1+s2+s3+.. )/(number of s’s). Be careful.

Classic Mechanics Problem – Newton’s three laws of motion

Newton’s three laws of motion is the most frequent topic that you’ll definitely be tested in high school or college mechanics physics courses. The first law is the law of inertia, which means objects will stay in the current motion (static or dynamic) unless an unbalanced force F applied. Second law is the formula F…

Electricity and Magnetism

This is one of the most common concepts that will be tested on your physics exam. Whether it tells you to solve capacitance, resistance, current, or volts, you should know how to use the correct formula for each problem.

Kinematics Equations Problem

One of the most important and basic concepts in physics is Kinematics. You will need to understand all of its formula and which to use in different problem sets. Here is a random sample problem below.
