Question

Shown in the diagram below is path A from point P1 to P2, along which a dog ran. Also shown is an arrow labeled B. P₁ a b A What do A and B represent in the diagram? C B Path taken by the dog P2 4 A represents the displacement the dog traveled, while B is a vector representing the change in position of the A represents the displacement the dog traveled, while B is a vector representing the distance of the dog. A represents the change in position the dog traveled, while B is a vector representing the distance of the dog. A represents the distance the dog traveled, while B is a vector representing the displacement of the dog.​

Answer 1

A represents the distance traveled by the dog, a scalar quantity, while B is a vector representing the displacement, which is the shortest path from the initial to the final position with direction. Here option A is correct.

Distance is the total length of the path covered by a moving object, regardless of the direction. It is a scalar quantity, meaning it has only magnitude and no direction. Distance is measured in units of length, such as meters, kilometers, etc.

Displacement is the shortest straight-line distance between the initial and final positions of a moving object, along with the direction. It is a vector quantity, meaning it has both magnitude and direction. Displacement is also measured in units of length, but with a specific direction, such as north, east, etc.

In the diagram, A is the curved line that shows the path of the dog from point P1 to P2. The length of this line is the distance traveled by the dog. B is the arrow that points from P1 to P2. The length and direction of this arrow is the displacement of the dog. Here option A is correct.
