What is the acceleration due to gravity on Earth?

The acceleration due to gravity on Earth is commonly rounded to approximately 9.81 m/s². This value represents the acceleration that an object experiences when falling freely towards the Earth, assuming negligible air resistance.

This acceleration is a result of the gravitational force exerted by the Earth, which pulls objects toward its center. The precise value of 9.81 m/s² can vary slightly depending on geographic location and altitude, but it is generally accepted as the standard value for calculations in physics.

While other options may present values that are close approximations, the most accurate and widely used value for the acceleration due to gravity at Earth's surface is 9.81 m/s². This understanding is crucial for solving problems involving projectile motion, free fall, and other dynamics related to gravity in physical science.
