Question
Give two differences between displacement and distance.
Advertisements
Solution
Differences between displacement and distance.
Distance:
- It is a scalar quantity.
- Distance travelled is always positive.
- The distance travelled by a moving body is the actual length of path.
- Distance travelled is always greater than or equal to the displacement.
Displacement:
- It is a vector quantity.
- Displacement may be positive negative or zero.
- The displacement of a body is the shortest distance between the initial and final positions of the body.
- Displacement is always less than or equal to the distance travelled.
Displacement is zero
