# Formula Oblique Throw Current height    Initial height    Initial vertical velocity    Time    Gravitational acceleration ## Current height

Unit
Height of a thrown (or launched) body at time $$t$$. The height is the vertical distance to the ground.

## Initial height

Unit
Initial height from which a body is thrown.

## Initial vertical velocity

Unit
Initial velocity in vertical direction. For example, the body could have been thrown at an angle, which is why it has a velocity $$v_{\text y0}$$. The total velocity of the body is $$v_0 = \sqrt{ v_{\text y0}^2 ~+~ v_{\text x0}^2 }$$ with $$v_{\text x0}$$ as initial velocity in the horizontal direction.

## Time

Unit
If you insert a time $$t$$ into the formula, you get the current height position $$y(t)$$ of the body.

## Gravitational acceleration

Unit
Gravitational acceleration is an acceleration of the body due to gravity. On earth it has the value $$g = 9.8 \, \frac{\mathrm m}{\mathrm s^2}$$. The minus sign in the formula says that the gravitational acceleration is directed against the $$y$$-axis ("upwards"), which here points against the falling motion.
