Distance and Displacement Meaning | Definition, Units – Motion in a Straight Line
We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.
Distance or Path Length Covered:
- The length of the actual path covered by an object is called the distance.
- It is a scalar quantity and it can never be zero or negative during the motion of an object.
- Its SI unit is metre.
Displacement Physics Definition:
- The shortest distance between the initial and final positions of any object during motion is called displacement.
- The displacement of an object in a given time can be positive, zero or negative.
Displacement, Δx = x2 – x1
where, x1 and x2 are the initial and final positions of object, respectively.
- It is a vector quantity.
- Its SI unit is metre.
