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?
The speed of an object in free fall near the earth's surface is always 9.8 meters (32.2 feet) per second morethan it was one second earlier.
Will density of a substance cause it to fall faster?
All objects fall at 32 feet per second per second, meaning that every second, they are falling 32 feet per second faster. Air resistance may have a minimal effect but the density of the object will not affect the speed.
If a object is moving at 400 miles per hour how many feet per second is this?
An object moving at 400 mph is traveling at: 586.7 feet per second.
Does an object dropped from twice as high take twice the time to fall?
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
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).
What is your speed in feet per second if you travel at 90 kilometers per hour?
At 90 km/h an object is moving at about 82.021 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.
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.
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.
How many feet per second does a pebble fall?
1 foot.
