So far, okay, so far we have discussed the addition and subtraction of two vectors. Now let’s see one more mathematical operation which is very much important for the understanding of various aspects of physics and that is the product of two vectors. So let us discuss the product of two vectors.

Depending upon the end […]

Let us consider a vector a. let’s say this is a vector a. Then what is the meaning of vector minus a. minus a that means a vector is multiplied by minus one. That means the vector is rotated by an angle of 180 degrees. So if a vector is multiplied by minus one that […]

Addition of two vectors. Case one. Case one. If we have magnitudes of two vectors. Magnitude of two vectors and angle between them. So we are planning to work out the addition or we are planning to work out about the resultant force, resultant vector in fact, if you know the magnitude of two vectors […]

We will start with the vector. Note down the definition of the Vector

A physical quantity is said to be vector quantity   if it carries direction as well as magnitude and it follows Triangle law of vector addition.

See when it comes to the understanding of vector, the definition includes 3 important aspects.

First, direction, quantity should carry […]

One example. Let’s write, position of a particle, position of a particle in its linear motion varies with acceleration, position of a particle in its linear motion varies with acceleration according to given function. Find the velocity at x = 2 meter if v = 0 for x = 0 meter per second. Acceleration of […]

Let’s discuss the definite integral. Let us discuss the definite integral. Now listen carefully. This is the indefinite integral of a function, okay. Now what we do is we integrate this function from one initial value to one final value. This is called definite integral of f(x), definite integral of f(x) with respect to x […]
