PHYIC CALCULATOR
Free Fall Calculator
A precise tool.
What is the Free Fall Calculator & How does it work?
Free fall is the motion of an object under the influence of gravity alone, without any other forces acting upon it. The distance fallen by an object in free fall can be calculated using the formula:
h = 0.5 times g times t^2
h = height, g = acceleration due to gravity (9.8 m/s²), t = time
The final velocity of the object can be calculated using:
v = g times t
v = velocity, g = acceleration due to gravity (9.8 m/s²), t = time

Frequently Asked Questions
How do I calculate the distance fallen by an object in free fall?
Use the formula h = 0.5 × g × t², where h is the height, g is the acceleration due to gravity (9.8 m/s²), and t is the time.
What is the final velocity of an object in free fall?
Calculate it using v = g × t, where v is the velocity, g is the acceleration due to gravity (9.8 m/s²), and t is the time.
Can I use this calculator for objects on the moon?
Yes, but you need to adjust the acceleration due to gravity to the moon’s value, which is approximately 1.63 m/s².
What units should I use for time in these calculations?
Time should be measured in seconds (s) for consistency with the standard gravitational acceleration of 9.8 m/s².
How does air resistance affect free fall calculations?
Air resistance can significantly affect free fall, especially at higher speeds or for objects with larger surface areas. This calculator assumes no other forces except gravity.
Can this calculator be used to determine the time it takes for an object to hit the ground from a certain height?
Yes, you can rearrange the formula h = 0.5 × g × t² to solve for time: t = √(2h/g).
What is the difference between free fall and projectile motion?
Free fall involves an object moving only under gravity, while projectile motion includes horizontal movement as well, typically due to an initial velocity.
