![]() Last, you need to understand the formula for the velocity of an object undergoing free fall.More detail on this can be found in our gravitational force calculator. Second, you need the mass of both objects.First, you need the height of the object.The following steps are required to calculate an object in free fall. Answer (1 of 6): Following the standard equation of motion: v2 - u2 2aS So since you say its free-fall, that means you dropped it, as in without any initial velocity, so u 0m/s. It should be noted that in a real-world application you would not be going so fast due to the resistance of airspeed. Using the time from above and assuming an initial velocity of 0, we get a final velocity of 442.66m/s. Next, we will need to calculate how fast you will be going to see if you can survive the fall…(hint you can’t). Using the formula above, we get a total time of 45.17 seconds.

Let’s assume you’re jumping from a height of 10,000 meters. Let’s assume that you’re going on a skydiving adventure, but everything goes wrong! How long do you have to live before you hit the ground and how fast will you be going.įirst, we will calculate the final time. Factoring in the time it takes to reach terminal velocity after exiting the aircraft, which is about 10 seconds, and then calculating a fall rate of 1000 feet. Let’s look at an example of how to calculate the kinematic values of an object in free fall. In reality, air resistance would usually be present, but free-fall problems typically exclude this. ![]() To calculate the time we use the following formula:įreefall is defined as the movement of one object to another through the force of gravity and under no other forces. attempt to answer that question using a data table that skydivers use to estimate their free fall time. To calculate the velocity of a free fall (excluding air resistance), multiply the acceleration due to gravity by the time of fall.Īll of these values are typically known in a free-fall problem except time. g is the acceleration due to gravity (m/s^2).
