1. True because The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6% that on Earth's surface or 0.166 ɡ.
2.Yes
3.Yes Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. ... This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field.
4.Weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.
5. If the Earth's gravity did just suddenly disappear we would no longer have a force keeping us on the ground. The Earth would keep spinning, as it does, but we would no longer move with it; instead, we would move in a straight line, upwards.
6. Actually, gravity is the weakest of the four fundamental forces. Because they both have mass, the two protons exert gravitational attraction on each other. ... Because they both have a positive electric charge, they both exert electromagnetic repulsion on each other.
