The value for acceleration due to gravity, denoted by g, is approximately 9.81 m/s² at the Earth's surface.

Here's a breakdown:

* Acceleration: This refers to the rate at which an object's velocity changes.

* Due to gravity: This means the acceleration is caused by the force of gravity.

* 9.81 m/s²: This means that every second, an object falling freely towards the Earth will increase its velocity by 9.81 meters per second.

Important Notes:

* Variations: The actual value of 'g' can vary slightly depending on factors like altitude and latitude. For example, 'g' is slightly lower at higher altitudes and at the equator.

* Other planets: The acceleration due to gravity on other planets will be different due to their different masses and sizes.
