Physics 2022 JAMB Past Questions - Question 15:  The acceleration due to gravity

Correct Answer

B

Explanation

The acceleration due to gravity on the surface of the Earth is approximately 9.81 meters per second squared. This value can vary slightly depending on location and altitude.

The acceleration due to gravity, often denoted as "g," is a constant that represents the acceleration experienced by an object in free fall near the surface of a celestial body, such as Earth. On Earth, the standard value for the acceleration due to gravity is approximately 9.8 meters per second squared (m/s²).

This means that if you were to drop an object near the surface of the Earth, neglecting air resistance, it would accelerate at a rate of 9.8 m/s² downward. The value of gravity can vary slightly depending on the location on Earth and is affected by factors such as altitude and latitude. However, for most everyday calculations, 9.8 m/s² is commonly used as an approximate value for the acceleration due to gravity on the surface of the Earth.
