Question

differences between distance and displacement Related:  Motion, Chapter Notes, Class 9, Science?

Answer

Distsnce - 1) Total path cover by an object
2) Distance cannot be 0
3) Distance is scalar quantity
Displacement - 1) Shortest distance cover between initial and final position
2) Displacement can be 0
3) Displacement is vector quantity

Answer

Distance - Total path covered by an object is called its Distance.                                                        Displacement - The shortest distance travel by an object from initial to its final position is called Displacement.

Answer

Distance:
Distance is a scalar quantity that refers to the total length traveled by an object. It is the actual path covered by an object during its motion. Distance is always positive and has only magnitude. It is measured in units such as meters (m), kilometers (km), or miles (mi).

Displacement:
Displacement is a vector quantity that refers to the change in position of an object. It is the straight-line distance and direction from the initial point to the final point of an object's motion. Displacement can be positive, negative, or zero, depending on the direction of motion. It involves both magnitude and direction and is measured in the same units as distance (m, km, mi).

Differences:
1. Definition: Distance is the actual path traveled by an object, whereas displacement is the change in position of an object from the initial point to the final point.
2. Scalar vs. Vector: Distance is a scalar quantity as it has only magnitude, while displacement is a vector quantity as it has both magnitude and direction.
3. Sign: Distance is always positive as it represents the total length traveled, whereas displacement can be positive, negative, or zero depending on the direction of motion.
4. Path vs. Straight-line: Distance considers the actual path taken by an object, which can be curved or irregular. Displacement, on the other hand, represents the shortest straight-line distance between the initial and final points.
5. Units: Both distance and displacement are measured in the same units, such as meters, kilometers, or miles.
6. Relation: Displacement can be equal to or less than the distance traveled. For example, if an object moves in a straight line without changing direction, the displacement will be equal to the distance. However, if an object moves in a curved path, the displacement will be less than the distance.

Summary:
In summary, distance refers to the total length traveled by an object, while displacement represents the change in position from the initial to the final point. Distance is a scalar quantity, while displacement is a vector quantity. Distance is always positive, while displacement can be positive, negative, or zero. Distance considers the actual path traveled, while displacement represents the straight-line distance between the initial and final points. Both distance and displacement are measured in the same units and have different values depending on the motion of the object.
