So what is the question?
If you want the kinetic energy, you can calculate the gravitational potential energy at the top (GPE = mgh), and then assume that all the potential energy gets converted to kinetic energy.

What forces act on something being dropped off a building?
Gravity
How do you find the mass of an animal?
Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.

If a rock weighing 2200 N is dropped from a height of 15 m what is its KE just before it hits the ground Remember weight is measured in newtons (N) and is equal to mass times gravity.?
33,000 J

How do the distance and mas affect the force of gravity between objects?
More distance = less gravity. More mass = more gravity.
If two balls are dropped from a building at the same time does the distance between them change?
Yes because they fall towards a center of gravity they will get closer to each other
What forces act on something being dropped off a building?
Gravity
What does mass mean in weighing?
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..

When you measure the force of gravity on you it is called?
"Weighing yourself."

What are some physics formulas for finding distance if you have mass and gravitational force?
If an object is dropped near the surface of a planet, then the distance it fallsduring the first ' S ' seconds after it's dropped is(1/2) (acceleration of gravity on that planet) (S2) .The object's mass doesn't matter, because it makes no difference.
What is one invention that would not work if you had no gravity on earth?
weighing machine
How can you determine the mass of an object without weighing it?
by size,volume and gravity
