11. Uniform linear motion (ULM)

Uniform linear motion refers:

 Linear motion: motion along a straight line.
Uniform motion: motion with constant speed, the instantaneous speed do not change over time.

Uniform linear motion is motion with a straight-line trajectory over the same distance in the same amount of time, that is, the speed and the velocity are constant over the whole trajectory.

A uniform linear motion (ULM) means that it has constant velocity (meaning that the speed, direction and sense do not change over time)

If a body has constant velocity it does not speed up, slow down or change direction. Its average velocity is the same no matter what time interval during the motion it is measured.

Equations for ULM

In all ULM, the instantaneous velocity is always the same, so we can say that this value and the average velocity are the same.

Using this equation, we can obtain other mathematical equations which allows us to calculate distance travelled or time taken:
