Free Fall Calculator [iPhone]

Free Fall Calculator is a physic calculator to find the velocity of a falling object, the height it drops from or total time object falling with constant gravity.

The result will calculate once any input are change, e.g. By input the gravity and the object height, the time travel and velocity are calculate automatically. Same thing happen when you input the velocity, the height/distance and the time travel are calculate automatically.

Features:
- Instant calculation
- Result are copy able to other apps
- Formulas are include as reference

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as gravity x time.

Free fall speed
Object is released to fall down under the influence of gravitational force with no initial velocity. The velocity of a falling object is
v = g*t
where t stands for time, g for gravity and v for velocity.

Free fall equation
s = 0.5 * g * t^2
where t stands for time, g for gravity and s for distance/height.

Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
