Average Velocity and Instantaneous Velocity

This video elaborates the meaning of velocity. It focuses on explaining the difference between Average Velocity and Instantaneous Velocity. Watch for more...

SYNOPSIS:

An example of Average Speed

This video explains Average speed using an example - Train station problem.

SYNOPSIS:

Introduction to Speed and Velocity

This video describes the basic difference between speed and velocity. It describes velocity as change in position vector over a period of time.

SYNOPSIS:

Position vector and displacement

This video represents displacement in terms of initial and final position vectors. Displacement has been shown as a vector starting at initial position vector and ending at final position vector.

SYNOPSIS:

Concept of Distance and Displacement

This video explains the basic difference between distance and displacement.

Displacement is the shortest distance/path between two points. Watch for more...

SYNOPSIS:

Unit Vector and its Significance

This video gives description of a unit vector along with its significance. 

It illustrates how a unit vector is used to represent a specific direction and how it is used to specify components of a given vector in the direction of unit vector.

SYNOPSIS:

Resolution of vectors into components

This video explains the process of breaking down a vector into its components. 

For simplicity purposes, a vector with components only along two axes has been considered.

SYNOPSIS:

A vector with components along x, y, z axes

In this video, the formula for magnitude of a vector, with components along all three mutually  perpendicular axes i.e x, y, z, has been derived. Basic understanding of finding out the magnitude of a vector is important.

SYNOPSIS:

Resolution of vectors

This video explains the process of breaking a vector into its components. 

For simplicity we have taken a vector with components along x and y axes only.

Synopsis:

Multiplication of vectors - Vector product

This video describes Vector Product or Cross product of two vectors.

SYNOPSIS:

Multiplication of vectors - Scalar Product

This video describes Scalar Product or Dot product of two vectors.

Scalar product is very important to understand the projection of one vector over another vector.

Analytical Method of Vector Addition

In this video, we derive the formula for addition of two vectors and 

the angle made by resultant vector is also obtained.

Subtraction of two vectors

This video describes how we can subtract two vectors by using vector addition techniques.

Polygon Law of Vector Addition

This video describes the Polygon law of vector addition.

The method illustrates how to add more than two vectors by connecting the head of first vector with the tail of second vector. In this method we displace the vectors so as to complete a polygon.

Equality of vectors and Addition of two vectors.

This video describes the conditions when two vectors can be said to be equal. 

It also explains addition of two vectors using 

Triangular law and Parallelogram law of vector addition.

Scalar and Vector Quantities

Now and then, in our student life, we have come across topic - Vectors and Scalars.

This video is first in series towards explaining Vectors and Scalars in a bit of detail.
