Question

A person travels a distance of 18 km towards east and returns along the same path and travels for 5 km distance covered by him and displacement produced by him​

Answer 1

$\large{\underline{\underline{\red{\bf{\hookrightarrow Answer\:with\: Explanation:-}}}}}$

When a person travels 18km towards east and then returns back 5km in the same path , then his displacement will be equal to the shortest distance between initial and final point . In this case since the person returns back 5km , so the displacement produced by him will be ( 18km - 5km ) = 13km .

But if distance travelled was asked then it will be equal to the total path covered by the man , irrespective of dirⁿ of motion .

$\underline{\purple{\mathscr{\leadsto MorE\: RelateD\: InformatioN.}}}$

• Displacement is a vector quantity.
• It is equal to the shortest distance between final and initial points.
• Displacement is always equal to or less than distance.
• Velocity equals to displacement covered per unit time.
• It can be calculated using vector law of addition.
