What is g?
g refers to the acceleration due to gravity. This is the rate at which objects fall toward a celestial body, like Earth, when dropped.
- This is a type of acceleration that is only caused by gravity.
- Since smaller objects have very small gravitational force, this is usually reserved for massive things.
- The SI unit of g is meters per second squared (m/s2).
- When we drop an object, the acceleration it experiences is due to the Earth’s gravitational pull.
- For the planet Earth, g has a value of 9.8 m/s2.
- g can change depending on where you are on Earth. It’s slightly different at the poles and the equator.
- Other planets have their own g values, based on their mass and size.
What is the Relation between G and g?
G is the gravitational constant that helps us calculate the force between two masses. On the other hand, g measures how fast objects fall due to gravity. The relation between G and g is given as g = GM/r2. In this article, we will learn about the relationship between G and g in detail.
