Question
Explain the following concept in your own words with everyday examples:
Distance
Advertisements
Solution
It is the actual path length covered by an object during its motion. It is a scalar quantity.
For example, when we go to a mall for shopping from our house and then return to the house, the distance travelled by us would be twice the distance between our house and the mall.

Calculate the distance and displacement in the following case:
A car travels at a uniform speed of 42 km/h. In 10 minutes, how much distance would it cover?
Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Justify your answer.
Displacement can be zero but distance never.
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
