**Free Fall (time)**: Computes the duration of time that an object will be in free fall based on the height and the acceleration due to gravity.**Free Fall (distance):**Computes the distance that an object will be in free fall based on the duration of the fall and the acceleration due to gravity.**Free Fall (Velocity at Impact)**: Computes the final velocity of an object after a free fall based on the height and the acceleration due to gravity.**Free Fall (Energy on Impact)**: Computes the kinetic energy at impact based on the height of free fall, acceleration due to gravity and the mass of the object.**Model Rocket Altitude**: Computes the estimated maximum altitude of a rocket based the distance from the launch point and the angle to top point of flight (zenith).**Object Height by Time to Drop**: Estimates the height of an object based on the time it takes for an object to drop from the top of it.**Elevation of Object (angles and separation):**Computes the height of an object based on two angle measurements and the distance between them.**Distance Traveled at Constant Acceleration**: Computes the distance traveled by an object after a period of time, based on its initial distance from the origin, initial velocity and a constant acceleration.**g (acceleration due to gravity at sea level)**: Acceleration due to Gravity (g) at sea level on Earth is 9.80665 m/s^{2}.
