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…

Read moreVelocity 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…

Read moreVelocity 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…

Read moreDistanceThe 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…

Read moreIf 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,…

Read moreA 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…

Read moreMagnitude 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…

Read moreDot or Scalar Product of two vectors a and b is defined as multiplication of magnitudes of both vectors and cosine of angle between them. Let’s say that we have two vectors which…

Read moreEarlier in other articles, I have talked about what are Physical Quantities in Science. Let me shortly explain again here and then we will be moving into discussing Scalar and Vector quantities. So…
