Vocabulary
A force that exists between any two objects that have mass.
gravity
Gravity pulls to the _______ of the mass.
center
Everything with mass has gravity.
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
When the forces acting on an object are equal, the forces are ________.
Balanced
As distance decreases, weight...
increases
The amount of "matter" found in an object is called?
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
An object in motion will stay in motion and/or an object at rest will stay at rest until an unbalanced force acts on it.
Newton's 1st Law
When objects are further away they have....
less gravity
Newton's 2nd Law states that forces cause acceleration and the greater the mass of the object, the less force is needed.
False, the greater the mass, the greater the force needed.
When you pick up a pencil, a _____ force is applied.
contact
As distance decreases, gravity...
increases
The amount of gravitational pull acting on an object...
weight
What are the two factors that affect gravity
mass and distance
The gravitational pull of the Sun creates tides.
False. It is the gravitational pull of the Moon that creates tides.
Newton's 3rd law states......
For every action there is an equal and opposite reaction.
When you drop a pencil, a _________ force pulled the pencil to the ground.
