GRAVITY DEFINEDGRAVITY DEFINED
Gravity is the tendency of objects with mass to accelerate towards each other
Gravity is one of the four fundamental forces (interactions) in nature.

Planets and GravityPlanets and Gravity
Since Jupiter is the largest planet, it has the most gravity.
Pluto has the least amount of gravity of all the planets

The further an object is away from another object, the force of gravity is weaker.
The further an object moves from the surface of the Earth, the less gravity it feels from the Earth.
Scientists on the Space Shuttle experience microgravity

Mass and Weight are two different Properties of MatterMass and Weight are two different Properties of Matter
MASS Mass is a physical property of matter that
explains how much matter is in an object
Mass does not change when gravity changes

WEIGHT Weight is a force which is
calculated by multiplying the acceleration of gravity
times mass. Weight can change when
gravity changes

IF YOU PULLED A MOUSE AND AN ELEPHANT WITH THE SAME AMOUNT OF FORCE, THE ELEPHANT WOULD RESPOND LESS TO PULLING EVEN IF HE DIDN’T PULL BACK AT ALL
THAT IS BECAUSE AN ELEPHANT HAS MORE MASS THAN A MOUSE

WEIGHTWEIGHT
An elephant on the Earth would weigh less on the Moon, because gravity is less on the moon.
An elephant’s mass would not change if he went to the moon
