Question

What does it mean to say that the gravity of the Earth is $9.8\mathrm{m}/{\mathrm{s}}^2$?

Answer 1

Gravity:

1. The force that pulls items toward the core of a planet or other entity is called gravity.
2. The acceleration imparted by the Earth to things on or near its surface is referred to as gravitational acceleration. It has a value of approximately $9.8\mathrm{m}/{\mathrm{s}}^2$.
3. Gravitational acceleration is denoted by “g”.

Mathematical representation:

$\mathrm{F}=\mathrm{mg}$

Here,

F is the force.

m is the mass.

g is the acceleration.

Therefore, the gravitational acceleration due to the Earth is $9.8\mathrm{m}/{\mathrm{s}}^2$.
