Write the difference between uniform and non-uniform motion?

Answer:

Uniform motion is a type of motion that is characterized as the motion of an object wherein the object moves in a straight line and its velocity remains unchanged along that line, regardless of the duration of time, as it occupies equal distances at equal time intervals.

Examples:

  • If a car’s speed is 10 m/s, it implies that in one second the car covers 10 meters. The speed is unchanged in each second.
  • Movement of the ceiling fan’s blades.

Non-uniform motion is described as the motion of an object wherein the object moves at different speeds and does not cover the same distance at equal time intervals, regardless of the duration of the time interval.

Examples:

  • If in the first two seconds, a car occupies 10 meters and in the next two seconds it covers15 meters.
  • A train’s movement.

The main difference between uniform and non-uniform motions are tabulated below.

Uniform motion

Non-uniform motion

Uniform motion has zero acceleration

The non-uniform motion has non-zero acceleration.

The uniform motion is identical to the actual speed of the object.

The non-uniform motion is different from the actual speed of the object.

Uniform motion covers equal distance at an equal time interval.

Non-uniform motion covers unequal distance at equal time interval.

In uniform motion, the distance to time graph shows a straight line.

In non-uniform motion, the distance to time graph shows a curved line.
