## Average and Instantaneous Speed

The average speed of a particle in a time interval is defined as the distance travelled by the particle divided by the time interval. If particle travels a distance s in time t1…

## Speed and Velocity Differences

Velocity of an object is defined as displacement divided by the time taken for displacement. The speed of a moving object is defined as total distance covered divided by time take to cover…

## Velocity

Velocity of an object is defined as displacement divided by the time taken for displacement. The SI unit of velocity is metre per second which can be written as m/s or ms-1. Velocity…

## Speed

The speed of a moving object is defined as total distance covered divided by time take to cover the distance. SI unit of speed is metre per second written as m/s or ms-1…

## Distance and Displacement

DistanceThe total length of the path travelled by an object during a given time is called the distance travelled or covered by the object in that time. It is a Scalar quantity and…

## Zero Vector

If we add two vectors a, b we get another vector but what if we subtract two vectors of equal magnitude. We will get a vector which have zero magnitude and no direction,…

## Vector Algebra

A Physical Quantity which has magnitude as well as direction is called a Vector Quantity or Vector. Symbol for denoting Vector Quantities are usually written as a letter with an arrow on top…

## Cross Product or Vector Product Explained

Magnitude of Cross or Vector Product of two vectors a and b is defined as multiplication of magnitudes of both vectors and sine of angle between them. Do note that cross or vector…
