Question

A toy robot moved from a starting point, traveling in a straight line at different speeds and then turning around and returning to the starting point at different speeds. What is the total distance that the toy robot traveled?

Answer 1

Answer:

The total distance is equal to the change in total position of the person, but the displacement of the person is zero.

Explanation:

• The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.
• The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and direction
• Since the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.
• If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
