An actual velocity is measured directly from an object's displacement-time graph while a theoretical velocity is calculated by using a mathematical equation or scientific theory.
Velocity refers to the rate of change in displacement (distance) of an object with respect to time.
Also, velocity is a vector quantity and this simply means that, it has both magnitude (speed) and direction.
Mathematically, velocity is given by the formula;
[tex]Velocity =\frac{displacement}{time}[/tex]
In an experiment, there are two (2) main types of velocity used and these include:
- Actual velocity: it is a velocity that is measured directly from a displacement-time graph and it represents the true velocity of an object or physical body.
- Theoretical velocity: this is a type of velocity that is taken as an accepted (known) value of velocity because it is determined by using a mathematical equation or scientific theory.
In conclusion, an actual velocity is measured directly from an object's displacement-time graph while a theoretical velocity is calculated by using a mathematical equation or scientific theory.
