ANSWER : TRUE

Explanation:
- 1 The force of gravity is to do with
objects falling. Weight is to do with
objects feeling heavy.
The force of gravity and weight are the
same thing.
- 2 Weight disappears if the air
disappears. This is why there is no
gravity on the Moon.
Weight is independent of whether
there is air or not.
- 3 The weight of an object increases
with its height above the ground.
The weight of an object actually
decreases with height above the
ground. This only becomes apparent
when the distance is large; for small
distances above the surface of the
Earth we assume that the force of
gravity is constant, so our weight
remains constant.
- 4 Weight and mass are the same
quantity.
Weight is the force due to gravity and
is calculated using Newton’s Law of
Gravitation. Weight = mass x
gravitational field strength of the
planet. Mass is the amount of matter
in an object.
- 5 Weight increases if the object is
compressed and decreases if the
object is spread out.
Weight does not depend on whether
the object is compressed or spread
out.
- 6 Moving objects try to overcome the
force of gravity as they move
upwards and cancel it out at the
point where they stop.
Moving objects slow down as they
move upwards against the force of
gravity. Objects speed up as they fall
down, as they are moving in the same
direction as the force of gravity.
Objects cannot cancel out the force of
gravity.
9 Heavy objects fall faster than light
ones.
They don’t if they are in a vacuum;
there they fall at the same rate. When
air is present, air resistance (friction)
slows them down. It isn’t always the
light one that is slowed down the most.
It depends on the shape of the object.
