❓ Quick answer
Why is the Moon not pulled into Earth if gravity acts on it?
The Moon is in orbit around Earth. Gravity pulls it toward Earth, providing the centripetal force needed for circular motion. The Moon's orbital velocity is just right so it falls around Earth rather than into it.
❓ Quick answer
How is g different at different latitudes?
Earth bulges at the equator and is flatter at the poles. At the equator, you are farther from Earth's center, so g is lower (9.78 m/s²). At the poles, you are closer, so g is higher (9.83 m/s²). Also, Earth's rotation creates a centrifugal effect that is maximum at the equator.
❓ Quick answer
Can escape velocity be exceeded?
Yes. Escape velocity is the minimum speed to escape gravity if directed correctly. Speeds exceeding escape velocity result in faster recession from the body. Escape velocity applies to objects starting from a body's surface or orbit; the direction matters for achieving orbit vs escape.
