What is the standard acceleration due to gravity on Earth?

The standard acceleration due to gravity on Earth is approximately 9.8 m/s². This value represents the rate at which an object accelerates towards the Earth when it is in free fall, neglecting air resistance. This acceleration is a fundamental constant in physics and is crucial for calculations involving gravitational force and motion near the Earth's surface.

It's accepted as a standard for many calculations in both educational contexts and scientific applications. The value 9.8 m/s² arises from the mass of the Earth and its radius, accounting for its gravitational pull. This precise measurement can vary slightly depending on geographical factors and altitude, but for most applications in physics at the National 5 level, 9.8 m/s² is used as the standard value.
