## x and y components of a vector

This article will teach you how to find the x and y components of a vector. We already know what vectors and scalars are and how important they are when we study physics. Finding vector components is the opposite of vector addition, where we find vector addition of two or more vectors. Here, a vector …

## Escape Velocity Formula

TL;DRThe escape velocity formula does not depend on the escaping object’s properties. The only thing that counts is the celestial body’s mass and radius. It is given by the relation$v_e = \sqrt{\frac{2GM}{R}}$ You’ve probably seen rockets launch into space. These rockets need a huge kick or push to leave the earth’s surface. This push is …

## Linear Motion Examples in Daily Life

Looking around, we would notice that there are many things in motion all around us. There are various types of motion that one may encounter in daily life. In this article, we will look at some examples of linear motion in everyday life, along with explanations. It is defined as an object’s tendency to move …

## Rectilinear Motion

What is Rectilinear Motion? Rectilinear Motion is a type of motion that occurs only along one axis or direction. It is also referred to as linear motion. Let us now learn about the meaning, definition, types, some examples, and physical quantities or parameters of rectilinear motion. Introduction We already know about motion, the most common …

## Vernier caliper

Introduction

Vernier caliper is introduced in 1631 by Pierre Vernier of France.It is instrument for making very accurate linear measurements It utilizes two graduated scales: a main scale similar to that on a ruler and an especially graduated auxiliary scale, the vernier, that slides parallel to the main scale and enables readings to be made to a fraction of a division on the main scale.

## 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 …

## Stable unstable and neutral equilibrium Questions for JEE Examination

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.
