2.

FLASHCARD QUESTION

Front

How does the force of gravity change with distance from the center of the Earth?

Back

The force of gravity decreases proportional to 1/r^2 as the distance r from the center of the Earth increases.

3.

FLASHCARD QUESTION

Front

What determines how far a projectile lands?

Back

The distance a projectile lands is influenced by its initial velocity, angle of launch, and the effects of gravity.
