Main Topic Supporting Detail
What is gravity A force of attraction between objects due to their mass
All objects experience an attraction toward all other
Earth’s mass is so large it makes gravitational pull of
all other objects on Earth unnoticeable.
Earth’s gravitational force pulls everything towards the
center of Earth.
Newton Described relationship between gravitational force,
mass, and distance
Applies to all objects in the universe.
Law of Universal All objects in the universe attract each other through
Gravitation gravitational force.
Gravitational force increases as mass increases
(ex. Elephant is harder to pick up than a cat because it
has a greater mass)
Gravitational force decreases as distance increases
Weight a measure of the gravitational force on an object –
(measured using a scale (n))
Mass amount of matter in an object (measured using a
Units of weight/mass Newton- SI unit for force (weight)
Kilograms, grams – SI unit for mass
Pound- standard unit for force (weight)
