Question

what acceleration does the force of earths gravity produce?
○ gravity does not produce an acceleration.
○ it changes direction every 9.8 meters.
○ 9.8 m/s/s
○ it varies depending on how long it has been falling.

Explanation:

• The first option is wrong because gravity does produce acceleration (objects fall due to it).
• The second option is incorrect as gravity's direction (toward Earth's center) doesn't change every 9.8 meters.
• The acceleration due to Earth's gravity near its surface is approximately \( 9.8 \, \text{m/s}^2 \) (or \( 9.8 \, \text{m/s/s} \)), so this option is correct.
• The fourth option is wrong because the acceleration due to gravity near Earth's surface is constant (ignoring minor factors like altitude), not dependent on fall time.

Answer:

C. \( 9.8 \, \text{m/s/s} \) (assuming the third option is labeled C; adjust label as per original question's numbering, but the correct choice is the one with \( 9.8 \, \text{m/s/s} \))
