Solution

Break Down the Problem

  1. Identify the Concept: The problem is asking for the acceleration due to gravity on Earth, which is a fundamental physics constant.

Relevant Concepts

  1. Understand Gravity: The standard value for gravitational acceleration at the surface of the Earth is approximately g=9.8m/s2 g = 9.8 \, \text{m/s}^2 directed downwards.

Analysis and Detail

  1. Direction of Acceleration: Gravity pulls objects towards the center of the Earth, which means the acceleration due to gravity is always in the downward direction.

Verify and Summarize

  1. Verification: The commonly accepted approximate value for acceleration due to gravity is 9.8 m/s² downward. This is universally recognized in physics.

Final Answer

The correct answer is b. 9.8 m/s² downwards.
