What is the approximate value of acceleration due to gravity on the surface of the Earth?

• A. 9.8 m/s²
• B. 10.0 m/s²
• C. 9.81 m/s²
• D. 11.0 m/s²

Answer: (A)

The value of acceleration due to gravity on the surface of the Earth is approximately 9.81 m/s². This standard approximation is commonly rounded to 9.8 m/s² for simplicity in many physics problems, making option A a valid choice. The acceleration due to gravity, often denoted as \( g \), signifies how quickly an object accelerates towards the Earth when dropped. The value varies slightly based on geographical location and altitude, but for most calculations, using 9.8 m/s² provides a close enough accuracy. Using the value of 10.0 m/s² simplifies calculations but is not as precise as 9.8 m/s² or 9.81 m/s², which are the more scientifically accurate figures. The option of 11.0 m/s² is significantly higher than the accepted values and does not reflect the actual conditions on Earth. Hence, option A represents a widely accepted and practical answer, making it a logical choice.
