What Is The Speed Of Free Fall?

Are you looking for the speed of free fall? Wait! Here we will give you everything regarding the free fall objects including their speed. In your school days, you might be heard a story of an apple and Einstein. In that, they said that Einstein had sat below an apple tree and an apple fell on his head. So, in this story, the falling apple is nothing but a free-falling object. Now, you may be curious to know, why any object falls on the ground instead of going upward. Right? Well, this happens because of the gravitational force exerted by the Earth on the falling object. Below we will discuss it in detail. Let’s have a look at the speed of free fall. 

What Is The Speed Of Free Fall? 

The average speed of free fall is around 5 m/s. The initial speed of fall is zero and takes a full second to reach 10 m/s so, the average of zero to 10 m/s is 5 m/s. It means during each second of free fall, the speed of an object increases before attaining zero. Similarly, a free-fall object falls on the ground with an acceleration of 9.8 m/s2. Therefore, this special value of acceleration is so important in Physics that it has its own peculiar name, the Acceleration of gravity, and its own peculiar symbol ‘g’. Here, you may be wondering how all the objects fall with the same acceleration regardless of their different weight and size. This is because they all have the same gravity and the air resistance is the same for each.

Here are the different speeds of the free fall, 

  • The speed of free fall skydiving is between 240 and 290 km/h
  • The speed of free fall object is 53 m/s
  • The speed of free fall in water is around 120 miles per hour
  • The maximum speed of free fall is 190 km/h or 118 miles per hour
  • The top speed of free fall is 190 km/h or 118 miles per hour

For example, you throw a ball upward. In this, initially, the ball was at the rest position with zero speed. When you throw it up, it attains some speed and at its highest height, it again attains zero speed only for a fraction of a second. After attaining zero speed, your ball again comes back with maxim speed and after falling on the ground it again attains zero speed. 

Let’s understand how to calculate the speed of the free-falling body. 

Calculate The Speed Of Free Fall 

To calculate the speed of free fall, you can use a free fall speed calculator. But here we will see a formula method to calculate the free fall speed. To calculate the speed of free fall the formula is given as, 

Vf = g x t 

Here, g – is the acceleration of gravity whose Constant value is 9.8 m/s2 

Let’s calculate the speed of the free-falling body that falls in 6 seconds from a certain distance. 

Let’s consider the formula given above 

Vf = g x t 

    = 9.8 m/s2 x 6s = 58.8 m/s

So, you can say, the speed of the free-falling object is 58.8 m/s for a 6s. 

About Free Fall 

Free fall is a state of acceleration in Physics. They are especially accelerating at a rate of 9.8 m/s2. This is to say that the velocity of a free-falling object is changing by 9.8 m/s every second. If dropped from a position of rest, the body will be traveling at 9.8 m/s or approximately 10 m/s at the end of the first second, 19.6 m/s or approximately 20 m/s at the end of the 2nd second. Similarly, for the third second, it will be at the speed of 29.4 m/s. From this, you can conclude that the free fall speed of any object is continuously increasing after attaining minimum speed. 

So, the speed of a free-falling body that dropped from a position of rest is dependent upon the time that it has fallen.

FAQ

Gravity will accelerate any object at a rate of 32 feet per second per second. But what do we do with that number? What it means is that if we fall for one second we’ll reach a speed of 32 feet per second.
A: Yes you can. It is said that in order for an object or a projectile to leave Earth’s gravitational pull, it must reach Earth’s escape velocity, meaning reach a speed of 7 miles per second(~11 km per second).
It takes very roughly 10 seconds to fall the first 1,000 feet and then about 5 seconds for every subsequent 1,000 feet – so if an experienced skydiver falls for about 10,000 feet before deploying their parachute they will have had roughly 60 seconds of freefall.
Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.

Is Speed Constant In Free Fall?

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.

How Long Does It Take To Fall 100 Ft?

2.49 seconds

How long does it take for an object to fall 100 ft? It takes 2.49 seconds for something to fall 100 ft (If the initial velocity is equal to zero and there is no air resistance.).

How Far Do You Fall In 10 Seconds?

Using the figure of 56 m/s for the terminal velocity of a human, one finds that after 10 seconds he will have fallen 348 metres and attained 94% of terminal velocity, and after 12 seconds he will have fallen 455 metres and will have attained 97% of terminal velocity.

Conclusion 

In this article, you got the speed of a freely falling body along with its formula. Free fall is a very common movement or motion which every day can be observed in daily life. If you drop something accidentally you can see its motion. In the beginning, it will have a low speed and until the end, it gains speed and before the collision, it reaches its maximum speed. Many factors are there to affect the speed of the falling body. The important factors are resistance due to air and the acceleration of gravity. Now, you understand the speed of free fall.
