1Define distance and displacement, and explain the difference with an example.
2Why is distance called a scalar quantity and displacement a vector quantity?
3In which situation is the value of distance not zero but the value of displacement zero?
4In which situation are distance and displacement equal? Explain why.
5When is displacement negative? What does the minus sign actually mean?
6Can the displacement of a journey ever be greater than its distance? Explain.
7A man goes out of his front door, walks once round his house covering 70 m and comes back in. What are his distance and displacement?
8Explain how distance can increase while displacement decreases at the same time.
9Rohit walks from A to B to C to D as in the figure, covering 5 m, 3 m and 5 m. Find his distance and his displacement.
10Why does displacement deliberately ignore the path that was taken?
