What is trajectory

Introduction to the concept of trajectory A trajectory is a path followed by an object with mass in curvilinear motion (curved path)  as a function of time. Mathematically, It is defined by the equation in x-y coordinates. A famous example would be projectile motion like the ball thrown at an angle or a bullet fired …

What is Equilibrium

A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.

Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.

You must have ride Roller coaster or ferris wheel in the amusement park. Its up and down and moving in the circle must have thrilled and fascinated you Today I would like to give a brief details about those machine and how you feel different in those rides. So this article is about the Physics of Amusement Park’s.

Charge Density Formulas and Solved Example

In this article, we would learn about charge density and its formulas and would also solve some problems related to this concept. We encounter electric charge density while calculating electric field from various continuous charge distributions like linear, surface and volume. We also need the concept of charge density while studying current electricity. What is Charge Density? …
