Translational Motion – equations, definition, types, examples

A particle is said to be in motion if it changes its position with time. Now, this change in position of the particle may be happened in many ways. The particle may go straight, may move in circular path, may spin around an axis, may roll on the floor. Considering these different ways of changing … Read more

Equations for Force in Physics | definition formula unit

We have already discussed Newton’s laws of motion in other three articles. We got the definition of force from Newton’s first law of motion and the formula or the equation of force was derived from the Newton’s second law of motion. In this article, we are going to discuss the definition, formula, units, dimension, types … Read more

Physics equations of projectile motion – derivation and list

The equations for linear motion and free fall are known to all. One can find the position, velocity, acceleration and energy of a particle moving in a straight line with constant velocity or constant acceleration. Now, if we throw an object at any angle with respect to the ground, it will not follow a straight … Read more

Work done by tension force – formula and derivation

In another article, we have discussed the tension of a string or rope. We found that tension of string is a kind of force. Again, we know that a body can move due to the application of external force. So, the work done by a body depends on the force on it. Then, it seems … Read more

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

What does newton’s first law of motion state? 1st law

In physics, the laws of motion are the very basic laws of classical mechanics part. Sir Isaac Newton gave three laws of motion. In this article, we are going to discuss Newton’s first law of motion, what does newton’s first law of motion state? Explanation of Newton’s 1st law of motion with examples. Contents in … Read more
