How to find tension in a string? | Theory & formula in physics

If you drop a ball from the roof of your house, then you will see that the ball is falling down due to the gravitational force. Now, attach the ball at one of the ends of a string and fix the other end of the string at somewhere on the roof. Then drop the ball … Read more

Derive Newton’s first law from second law – prove

We already have discussed Newton’s first law and second law in other articles. These two laws deal with the motion of any particle in classical limit. First law gives the cause of motion and second law gives the measurement of force required to apply to make a particle in motion. That means these two laws … Read more

Newton’s fourth law of motion | Newton’s 4th law

Newton’s laws have brought the revaluation in Physics in 19th century. These laws have important roles in science. But, how many laws does Newton have? The answer is that Sir Isaac Newton have introduced many laws in many branches of science. He has huge contribution in most of the branches. Here, we are interested on … Read more

Newton’s second law of motion with example – 2nd law

The three famous laws of motion given by sir Isaac Newton are the basic laws in classical mechanics. These three laws describe the rest or motion state of an object. We already have learned the Newton’s first law of motion and its importance. Now, in this article, we are going to explain Newton’s second law … Read more
