Question

1. compare and contrast the two terms, distance and displacement. write one similarity and one difference in the meaning of these two terms.

similarity:

difference:

Explanation:

• Similarity: Both distance and displacement are related to the motion of an object and have the same SI unit (meter, \(m\)) and are used to describe the spatial relationship of an object's motion. For example, when an object moves along a straight line without changing direction, the magnitude of distance and displacement can be equal.
• Difference: Distance is a scalar quantity that refers to the total length of the path traveled by an object, regardless of direction. Displacement is a vector quantity that refers to the shortest straight - line distance between the initial and final positions of an object, and it has a direction associated with it. For example, if an object moves in a circular path and returns to its starting point, the distance traveled is the circumference of the circle, but the displacement is zero.

Answer:

• Similarity: Both are related to an object's motion, have the same SI unit (meter), and describe spatial aspects of motion.
• Difference: Distance is scalar (path length, no direction); Displacement is vector (shortest straight - line between start and end, with direction).
