What is gravity acceleration?

All objects, regardless of size, fall at the same speed: acceleration of gravity. This is the speed at which the object is free. This means that it is the speed at which the object accelerates towards the center of the Earth. This value is not constant, but changes with the location of the free -falling object. This means that the object accelerates 32.2 feet/s (9.8 m/s) for each second that falls. In other words, the longer the object falls, the faster it falls. Think of it as a car that constantly accelerates. The car would continue faster and faster, the longer it was driven. Similarly, the object falling for three seconds will be faster than an object falling for one second.

acceleration of gravity to a large extent depends on the surface that the object falls. Many of us will only experience gravity as the country is concerned, but Number changes dramatically if we were on another heavenly body. For example, acceleration of gravity is much less on the moon. In fact, this is the sixth value of the country, the value of approximately 5.3 ft/s ²

(1.6 m/s 2 ). The object falls towards the moon much slower.

Using equation, g = gm/r 2 , it is possible to calculate the acceleration of gravity of different objects in the space. The equation is G Gravity, G is a gravitational constant, r is the radius of the planet and M is the weight of the planet. Physicists who perform calculations have determined that acceleration of gravity on Jupiter is approximately 85.3 feet/s 2 (26 m/s ^{2 ). On the other hand, Pluto has 2 ft/s (0.61m/s}

2 ). You can see that planets with greater weight have greater gravity acceleration than planets with less weight.

If the world was a vacuum, these values ​​would be a real life. On the moon there is air vacuum, so objects fall to the ground when accelerating the gravity of the moon. On the ground, however, we have air resistance-the air pushes against the object when it falls. That's why the feathersIt floats on the ground while the bowling ball pierces, although gravity affects both objects the same. In order to accurately calculate the speed at which the object falls, the air resistance must be charged.
