At what rate do falling objects fall at?

Question

I understand that the speed increases per second per second until a maximum rate is reached - what are the logistics

Answer 1

9.8 m/s squared

Answer 2

The pull of gravity causes the downward speed to change by 9.8 meters/sec every second. So (for example) if something is falling at a rate of 30 m/s at a particular instant, then 1 second later it will be falling at a rate of 39.8 m/s (30 + 9.8).

At least that's the theory. In reality, air friction intervenes. As the downward speed increases, the upward force of friction also increases. After a certain point, the upward friction exactly balances the downward pull of gravity. At that point, according to Newton's 1st & 2nd laws, the speed stops changing and the object maintains that speed until it hits the ground. That speed is called "terminal velocity" and it is different for different objects; it depends on the size, shape and weight of the object.

Answer 3

On Earth speed increases by 9.8m/s^s until resistance of air or water (as in a sinking ship) limits velocity. Lunar gravity is about 1/6th of Earth's so any object would fall slower there than in a vacuum on Earth. But if an object falls into a Black Hole I don't think anybody knows for sure what happens.

Answer 4

the speed increases at the rate of 32 feet per second every second. whic h is about 22 miles per hour every second. The maximum speed depends on the shape of the object and how much resistance to the wind it presents. QED
For people, it's about 200 miles per hour.

Answer 5

Velocity = Initial Speed + (acceleration x Time)

So under gravity at 9.8 ms-2 if you drop something it gets faster at a constant rate (without air friction). That's why the feather and hammer hit the ground at the same time when dropped on the moon. Weight doesn't come in to it.

Drag is related to velocity and the "drag factor" of the object. For humans it's about 180mph. Takes around about 10 or so seconds...tho its a bit late for me to be doing sums!! LOL

Answer 6

When I went on a parachute jump in 1985, we were told that you fall from the aircraft at 120 mph from a standing start and this speed does not increase. From 2,000 feet it would take 18 seconds to hit the ground. (Instructions for deploying reserve shute in an emergency).

Answer 7

Falling objects fall in vacuum with gravity aceleration of 9.8 m/s^2.
It means that every second the velocity increases in 9.8m/s.
In air, velocity is affected by air resistance and form of the object.

Answer 8

9.8 metres per second every second,
9.8ms after 1 sec
19.6ms after 2 sec
etc...the air resistance usually stops things around 100 to 160 miles per hour depending on the shape

Answer 9

it depnds at what heght it falls from and how long it falls for because the fatser the object goes the heavier it gets but the longer the object falls the faster it gets and it also depends on the objects origonal weight and sze to dtermine the true answer.
so the answer to this question is that the rate is varied.

Answer 10

In Imperial 32ft/second/squared

Answer 11

objects fall at a rate of 9.81 m/s^2 or 32ft/s^2 (approx), but varies if the object is like paper or leaves, feathers etc.
