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;

$Velocity =\frac{displacement}{time}$

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.

Theoretical velocity is based on assumptions. Real velocity is measured during an experiment. Usually real velocity is slightly less due to friction forces.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
