Question
What is the acceleration due to gravity on Earth?
Select one:
- a.
10 m/s²
downwards - b.
9.8 m/s²
downwards - c.
10 m/s²
upwards - d.
9.8 m/s²
upwards
Solution
Break Down the Problem
- Identify the Concept: The problem is asking for the acceleration due to gravity on Earth, which is a fundamental physics constant.
Relevant Concepts
- Understand Gravity: The standard value for gravitational acceleration at the surface of the Earth is approximately directed downwards.
Analysis and Detail
- 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
- 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.
