Why does that happen? Again, because of air resistance. Or at least that's what science says! If you try to perform an experiment, you'll notice that, in reality, the brick falls to the ground first. If you drop a feather and a brick, they will hit the ground at the same time. It means that with each second, the falling body travels a substantially larger distance than before.Īnother interesting fact is that according to the free fall formula, the distance does not depend on the mass of the falling object. You can immediately see that the object distance traveled is proportional to the fall time squared. If the object is already traveling with an initial velocity, you have to take it into account, too: s = v₀t + (1/2)gt² If the initial displacement and velocity are both equal to zero, it boils down to: s = (1/2)gt² If you want to calculate the distance traveled by a falling object, you need to write down the equation of motion. If you want to consider it, head over to our free fall with air resistance calculator. In this free fall calculator, we neglect the influence of air resistance. According to Newton's first law, at that point, the falling body stops accelerating and moves at a constant speed. At some point, the two forces become equal in magnitude.
The force of air resistance, however, increases with increasing free fall speed. What is the terminal velocity? As you have seen above, the free fall acceleration is constant, which means that the gravitational force acting on an object is constant, too. In reality, though, a falling object's velocity is constrained by a value called the terminal velocity. Without the effect of air resistance, each object in free fall would keep accelerating by 9.80665 m/s (approximately equal to 32.17405 ft/s) every second. g is the free fall acceleration (expressed in m/s² or ft/s²).t stands for the fall time (measured in seconds) and.v₀ is the initial velocity (measured in m/s or ft/s).From the definition of velocity, we can find the velocity of a falling object is: v = v₀ + gt
