A: ### Quick Answer

**On Earth, a free-falling object accelerates at 32 feet per second.** This means that after two seconds the object is falling at 64 feet per second, and after three seconds it's travelling at 96 feet per second, and so on.

The object's velocity continues to increase at the same rate until it reaches its terminal velocity, which is when air resistance equals the force of gravity. When the terminal velocity is reached, a free-falling object can no longer accelerate. In a vacuum, a feather falls at the same rate as a hammer because there isn't any air resistance to slow either object down.

## What is 9.8 m/s^2?

A:

Full Answer >**The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth.**The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.Filed Under: - Q:
## How many times per day does lightning strike Earth?

A:

Full Answer >**Lightning strikes reach the ground on Earth as much as 8 million times per day or 100 times per second, according to the National Severe Storms Laboratory.**Out of all the lightning strikes in the world, the United States accounts for about 20 million of the total number of lightning strikes each year.Filed Under: - Q:
## How do you calculate how many feet are in something?

A:Calculating how many feet are in something requires two steps: measuring the object and then converting the measurement into feet. The measurement can be made from any metric or English measurement of length, but the conversion requires knowing the ratio of the particular unit of measurement used to one foot.

## How many miles per hour are equal to 300 feet per second?

A:

Full Answer >**When converting from feet per second to miles per hour, 300 feet per second are equal to 204.55 miles per hour.**To find this answer, it is necessary to use the conversion factor that 1.0 feet per second (fps) is equal to 0.68182 miles per hour (mph).Filed Under:
