The acceleration of a free falling object is 32 feet per second per second. This is acceleration due to gravity. This is, of course, not the velocity of the falling object, but if you know a little bit more about the falling object you can figure out its velocity using constant acceleration formulas:
: : : : For example:
If you are standing on the top floor of the Eiffel tower, which is 896 feet above ground, and drop something out of the window, you can calculate how fast it is going just before it hits the ground using equation 4.
vi = 0
s-si=896 feet
a=32 feet/second/second
Plugging in our values, we find that the object would be traveling at 239.466 feet/second.
You could also figure out long it takes to reach the ground using either equation 2 or 3.
This is, of course, an ideal case where there is no wind or air resistance.

If an object is in free fall after each second how does the object fall?
In free fall, the object accelerates downward at a rate of 9.8 m/s^2 due to gravity. After each second, the object's velocity increases by 9.8 m/s. This means that the object falls faster and faster with each passing second.
One object has a velocity of -4 feet per second another has 3 feet per second which is greater?
The object with the velocity of -4 feet per second is going faster than the other, but in the opposite direction, hence the minus sign.
How many feet per second at 71 mph?
An object moving at 71 miles per hour travels 104.1 feet per second.
If weight is added to a object will it go fast or slow?
Depend on if you are talking a "free-fall" or an object descending the side of a mountain. Free-fall all objects regardless of weight fall at the same rate of speed (36 feet per second).
If a object is moving at 400 miles per hour how many feet per second is this?
400 miles per hour is equivalent to 586.67 feet per second. To convert miles per hour to feet per second, you can use the conversion factor that 1 mile is equal to 5280 feet and 1 hour is equal to 3600 seconds.
How much does the earth gravity cause an object to accelerate?
The acceleration due to gravity on Earth is approximately 9.81 meters per second squared. This means that for every second an object is in free fall near the surface of the Earth, its speed increases by 9.81 meters per second.
How many feet per second do you fall when skydiving?
Well the average terminal velocity ofr an average sized jumper is 120mph. I fall at 120mph and fall 10,000 feet in 45/50 seconds so I guess about 213 feet per second.
If an object travels at 4.5 feet per second how many feet does it travel in one hour?
16,200 feet per hour.
Will density of a substance cause it to fall faster?
No, the density of a substance does not affect how fast it falls in a vacuum. In a vacuum, all objects fall at the same rate regardless of their density due to gravity. It is only in a medium like air that density can play a role in how fast an object falls due to air resistance.
Does an object dropped from twice as high take twice the time to fall?
No, an object dropped from twice the height will not take twice the time to fall. This is because the time it takes for an object to fall depends on the initial velocity and acceleration due to gravity, not just the height from which it is dropped.
How many feet per second does a pebble fall?
1 foot.
What is the rate of acceleration for a falling object?
Near the surface of the Earth, the rate of acceleration due to gravity is equal to 32 feet per second per second, or 9.8 meters per second per second. That means that if you release an object from a tall tower, the object will fall. After one second, it will be traveling at 32 feet per second, and will have traveled 16 feet. After 2 seconds, it will be traveling at a speed of 64 feet per second, and will have fallen 48 feet. In the absence of air resistance, the object will continue to accelerate at this rate, speeding up until it hits the ground. Far from the Earth, the acceleration of gravity depends on the distance to the object; the force of gravity falls off by the square of the distance. Around other planets or moons, the force is proportional to the mass of the planet.
