Question #c7491

Answer 1

False

Explanation:

Gravity (on Earth) is a downward force directed toward Earth's core (the center of its gravitational field), and everything on Earth (and to an extent, outside Earth's atmosphere) is affected by this force. This explains common phenomena like why you must push down on Earth's surface to move upward, like when you get out of a seat, or why it requires effort (called work in physics) to pick up an object; if no gravitational force were present, picking up a heavy object would seem effortless.

(This is evident when you picture the concept of weight: Weight is the force experienced by an object from the pull of gravity. On the Moon, where the acceleration to due to gravity is about `1/6` of that of Earth's, an object there weighs `6` times less than it would here on Earth.)
