To calculate how far Harry Potter fell in Prisoner of Azkaban during the Quiddich match. Next, measure the velocity … To calculate the force of a falling object you must first discover the velocity that object is traveling at, once this has been calculated you can then discover the Kinetic Energy of that object. The equations you described are for Kinetic Energy and Potential Energy. I did my egg drop project. Force Calculator. I’d like to know how to calculate the force of a falling 30 kg object from 5m high. Objects falling on the ground at low speed can be considered being in free fall because in this case the air resistance is negligible and can be neglected. Likely errors are of the order of a factor of 10 for this sort of calculation. When the payout rope is four metres, a fall of two metres is more uncomfortable than a fall of one metre. The fall factor is a measure of the "force" of the fall. If an object is dropped from height h = m, then the velocity just before impact is v = m/s. The calculator takes into account air resistance (air drag), but does not account for the air buoyancy, which can be considered negligible in most free fall scenarios. But this force is 657.27 N which is the same as the force of me standing on the ground. The symbol of Force is 'F' and its measured in the SI unit of Newton. This type of energy is known as gravitational potential energy and it is equal to the object's mass multiplied by the height from which it was dropped and the acceleration due to gravity: PE=mgh.
