Description of the free fall speed
The free fall speed of an object can be calculated using the formulas for free fall, neglecting air resistance. The formula is:
The velocity \(v\) at the end of the fall time \(t\) is:
\[v=g*t\]
The fall distance \(s\) is:
\[s=\frac{g}{2}·t^2\]
The velocity at the end of the fall height \(h\) is:
\[v=\sqrt{2·g·h}\]
Where:
- \(v\) is the fall velocity (in m/s)
- \(g\) is the acceleration due to gravity ( \(≈ 9.81 m/s^2\) )
- \(t\) the fall time (in s)
- \(h\) the fall height (in m)
