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.
