Gravity
What is Gravity?
Gravity is the force that pulls objects towards each other. It is the force of attraction between any two objects that have mass.
Gravity is the force that pulls objects toward each other.

Planets orbit the sun
Objects fall to the ground
Astronauts float in space
Gravity only exists on Earth.
True
False
Law of Universal Gravitation
- Newton was the first one to suggest that gravity is universal and affects all objects in the universe.
- Universal gravitation means that the force that causes an apple to fall from a tree to the ground is the same force that causes the moon to keep moving around Earth.
- Newton’s Law of Universal Gravitation states that the force of gravity affects everything with mass in the universe.
What 2 things affect gravity?
MASS
DISTANCE
The force of gravity between two objects decreases as the distance between them increases.
True
False
Why does an apple fall down?
Mass of apple= 0.1 kg
Mass of human = 62 kg
Mass of Earth= 6 x 1024 kg
Compare the mass of the moon to the mass of the Earth.

A 50 pound child on Earth would weigh...
Weight = mass x gravity
Weight is the force of gravity on an object. It changes with location!
Weight is a force measured in Newtons.
