# Formula: Horizontal throw Throw distance    Initial speed    Initial height

## Throw distance

Unit
The throw distance (generally: flight distance) is the distance from the throw/launch point to the place where the body lands on the ground. We can also replace the root term in the formula with the flight duration $$t_{\text d}$$: $w ~=~ v_0 \, t_{\text d}$

## Initial speed

Unit
This is the speed in horizontal direction with which a body is thrown / launched.

## Initial height

Unit
Initial height is the distance from the throwing/launching position to the ground.

## Gravitational acceleration

Unit
Gravitational acceleration is a constant acceleration experienced by all freely falling bodies near the ground. It has the value: $$g ~=~ 9.8 \, \frac{\mathrm m}{\mathrm{s}^2}$$
