There are many ways to experience the thrill of a free fall - you could, for example, jump with a parachute or try bungee jumping!
Technically, such a jump doesn't fulfill all the requirements of a free fall - there is substantial air resistance involved.
We'll also explain what is the free fall acceleration and why we assume it's constant.
Make sure to have a look at the projectile motion calculator, which describes a particular case of free fall combined with horizontal motion..
Another interesting fact is that according to the free fall formula, the distance does not depend on the mass of the falling object. If you dropped the two items in a vacuum, they would both hit the ground at the same instant!
If you drop a feather and a brick, they will hit the ground at the same time... If you try to perform an experiment, you'll notice that in reality, the brick falls to the ground first. You might already have learned the free fall equation, but it's one thing to understand the theory and a completely different one to experience it.
The block begins to fall under only the effect of gravity.
At the instant that the block is 2.0 meters above the ground, the speed of the block is 2.5 meters per second. We can then apply this information to get the total energy when the block is released and the total energy at the 2.0 meter above-the-ground point.
You can immediately see that the object distance traveled is proportional to the fall time squared.
It means that with each second, the falling body travels a substantially bigger distance than before.
