Science chapter motion notes in very simple way | pdf or web view | S. Chand


What is Motion?


A body is said to be in motion when it’s position is changes continuously with respect to a stationery object taken as a reference point. 


What is Distance? 


The actual path covered by a moving body is called Distance that is travelled by a body. It is  a scalar quantity.


What is displacement? 


The shortest distance between the initial and final position is called displacement. It is a vector quantity. 


What is Uniform motion?

A body has a uniform motion when it travels equal distance in intervals of time.


What is Non-Uniform motion? 

A body has a non-uniform motion when it travels unequal distance in intervals of time. 


What is speed?

Distance travelled by a body per unit time is called speed. 


What is Velocity?

Displacement produced by a body per unit time is called Velocity. 


What is Acceleration? 

Change in Velocity(final velocity – initial velocity) upon change in time is called acceleration.

Equation of uniformly accelerated motion:-


1.First equation of Motion

The first equation of Motion is as follow :


V = u + at


In the above equation u Is initial velocity, V is final velocity, a is Acceleration and t is time. This is usually used to find the final velocity when distance is not given but acceleration, initial velocity and time.


2.Second equation of Motion

The second equation of Motion is as follow :


S = ut + ½ × at²

In the above equation, S is Distance,  u Is initial velocity, a is Acceleration and t is time. 

This equation is used to find the distance when final velocity is not given.

3.Third equation of Motion 

The equation of Motion is as follow :

v² = u² + 2as

In the above equation, s is Distance,  u Is initial velocity, V is final velocity, a is Acceleration and t is time. This usually help us to find finally velocity when time is given.

What is Clip Art in PowerPoint

Pictures perform a very good role in making our presentation effective, good-looking. In this article, we learn how to insert images as well as what is clip art. A single piece of ready made art is called Clip Art. Clip Art Gallery is the place where these ready single piece of art is stored. In this gallery different types of clips related to schools,computer, books etc. You can also insert a Clip Art ( A ready made picture) by performing the following steps. 1. Click on Insert menu. 2. Select Clip Art option.     The clip art pane will appear on right hand of the window. 3. A Search box appear, type the keyword related to the picture you are looking for.   4. Press Enter button OR Click on go button.   5. Select the picture which you want to insert in your slide. The selected picture will be inserted in your slide.

Overhead Projectors (defination, working, uses, advantages and disadvantages) | HPBOSE

Projectors are basically used for presenting our ideas among others. In starting Projectors are mainly used in educational fields. Today we use projectors in educational fields as well as in business fields. In this article, I will show the projectors used in past that is Overhead Projectors. This topic is also listed in HP board computer science syllabus. Let's start with his definition. What is Overhead projector? Overhead projectors or OHP's are the type of projector used for project images on large flat wall. It has a flat transparent top and a light source beneath transparent top and reflecting mirror and a fan to cool it. Above the box there is a long arm that has a mirror to catch and redirect the light towards the screen. Uses of Overhead Projectors  OHP is one of the most frequently used tool in education and training. Today, we use digital projectors in the place of OHP which is smaller in size as compared to OHP. Advantages of OHP 1. OHP's not much g...
