What are some examples of linear movements

Uniform movement

In this section we are concerned with the uniform motion of physics. In this chapter you will learn what it is all about, what the formulas are and how to use them.

With regard to the movements, we would like to start with what is known as the uniform movement. We try to explain this as simply as possible and also deal with the conversion of units (kilometers to meters, hours to seconds, etc.). However, there are a few very basic things about mathematics that you should know. If, while reading the following section, you realize that you are having math difficulties, please read the articles under the links below. Everyone else can save this:

What is uniform motion?

Uniform motion has the following properties:

  • The speed of the object is always the same
  • The acceleration a is zero (a = 0), i.e. the object is neither decelerated nor does it get faster


Or expressed as an example: You are driving on a road at 100 km / h. As long as you really drive the 100km / h, this is a uniform movement. On the other hand, if the speed changes, you no longer have a uniform movement.

How do I calculate a uniform motion (formula)?

The formula of uniform motion sets the information Distance, speed, time and starting distance in relation to each other. The following is the general formula and the meaning of the symbols. Then we will provide you with some explanations and examples.

Uniform motion formula:

  • s = v t + s0
  • "s" is the distance in meters [m]
  • "v" is the speed in meters per second [m / s]
  • "t" is the time in seconds [s]
  • "s0"is the starting distance in meters [m]

In very many cases the starting path does not exist. This simplifies the formula too

s = v ยท t.

Uniform movement: examples

Time for a few small examples of uniform movement. One thing is very important: you have to insert the numbers in the form in which they were given in the formula. Say the distance in meters and not in kilometers or centimeters. Or the time in seconds and not in hours. If you don't pay attention to this, you will quickly get crap out of arithmetic.

Example 2:

Tip: In any case, do the math for our exercises! This is the only way to get fit when calculating with the uniform movement!

Conversion of units

Many students have problems converting units. For this reason, we are going to give you a brief summary of the most important conversion rules.

  • 100cm = 1m = 0.001km
  • 1m / s = 3.6km / h
