true
What happens if the distance between objects with mass increases?
gravitational pull weakens.
As distance decreases, mass...
stays the same
A push or pull that is applied to an object.
force
When objects have more mass their gravitational pull is?
greater, bigger, larger, more gravity
Gravity is an attractive force that pushes.
false, it only pulls

mass
In space, what remains constant? What changes?
mass is constant, weight changes
More weight means less gravitational pull.
false, it would mean more gravitational pull
What happens to gravity if mass is decreased?
less gravity, it decreases
As distance increases, weight...
decreases

orbit
When objects are further away they have....
less gravity
Earth has more gravity than the Sun because it is denser.
false, the Sun has more mass, therefore it has more gravity

False. It is the gravitational pull of the Moon that creates tides.
How does one become weightless?
Remove gravity
If the Sun were to disappear, what would happen to the planets?
They would no longer be in orbit.
