What is the effect of gravity on an object thrown upward?

• A. It causes the object to float indefinitely.
• B. It will accelerate the object upward continuously.
• C. It will eventually pull the object back down.
• D. It will prevent the object from leaving the ground.

Answer: (C)

When an object is thrown upward, the force of gravity acts continuously on it, exerting a downward pull. This gravitational force opposes the initial upward motion of the object. As the object ascends, it slows down due to this force, eventually reaches a peak height where its velocity becomes zero, and then begins to fall back toward the ground. Gravity ensures that no matter how high the object goes, it will ultimately reverse direction and descend back to Earth. This is a fundamental principle of gravity's role in motion, demonstrating how it affects the trajectory of objects in free fall.
