Expert Answer:

Differences between uniform and non-uniform motion:

Uniform motion

Non-uniform motion

  • Movement of a body along a straight line with steady speed.
  • Movement of an object along a straight line with variable speed.
  • Covers equal distances in equal time interval.
  • Covers unequal distances in equal time interval.
  • Average speed is similar to actual speed of the object.
  • Average speed is different from actual speed of the object.
  • Distance-time graph shows a straight line.
  • Distance-time graph shows a curved line.
  • Rectilinear motion has zero acceleration.
  • Rectilinear motion has non-zero acceleration.

2) The shortest path between the initial and the final point is known as displacement. It is a vector quantity. Displacement can be 0, positive and negative.
