Gravity
•
Any object with mass exerts a force of gravity that
pulls on objects around it.
•
The more
mass
an object has, the
greater
its pull
of gravity.
•
Gravity keeps you from floating off into space.
Gravity helps keep the moon in orbit around the
Earth.
•
Gravity also keeps the Earth in orbit around the
Sun.
Gravity
•
Just as you are attracted to Earth, Earth is
attracted to you. You notice only the force that
Earth exerts on you because the force you exert
on Earth is so much smaller.
•
The force of gravity depends on two factors:
mass
and
distance
.
Gravity
•
Think about an apple falling from
a tree on Earth. Both the apple
and the Earth pull on each other
because they both have mass.
But the apple’s mass is so small,
its force of gravity is very small.
It does not pull very strongly on
Earth.
Gravity
•
Earth has much more mass than the apple. That
means that Earth’s force of gravity is larger than
the apple’s force of gravity. Earth’s gravity pulls
the apple down to the ground. As the apple falls,
its gravity actually pulls Earth up a very small
distance. But Earth moves only the tiniest amount
because Earth’s pull is so much greater than that
of the apple.
Distance and Gravity
•
As objects move
closer
together, their pull on
each other grows
stronger
.
•
As objects move farther
apart
, their pull on
each other
weakens
.
Gravity
•
Think of a spacecraft traveling toward another
planet. As the spacecraft moves away from
Earth, Earth’s pull on it decreases. As the
spacecraft moves closer to the other planet, that
planet’s pull on the spacecraft increases.

How does mass affect gravity?
Objects with mass exert gravitational force, influencing each other based on mass and distance. Gravity, a fundamental force, keeps objects like Earth and the moon in orbit and affects how objects fall towards each other. The relationship between distance and gravity is crucial, affecting the strength of gravitational pull as objects move closer or farther apart.

Gravity How Distance and Mass Affect Gravity
Notes Write down the words in yellow. The words in white are discussion points, you may write these down, but are not required.
Gravity Any object with mass exerts a force of gravity that pulls on objects around it. The more mass an object has, the greater its pull of gravity. Gravity keeps you from floating off into space. Gravity helps keep the moon in orbit around the Earth. Gravity also keeps the Earth in orbit around the Sun.
Gravity Just as you are attracted to Earth, Earth is attracted to you. You notice only the force that Earth exerts on you because the force you exert on Earth is so much smaller. The force of gravity depends on two factors: mass and distance.
Gravity Think about an apple falling from a tree on Earth. Both the apple and the Earth pull on each other because they both have mass. But the apple s mass is so small, its force of gravity is very small. It does not pull very strongly on Earth.
Gravity Earth has much more mass than the apple. That means that Earth s force of gravity is larger than the apple s force of gravity. Earth s gravity pulls the apple down to the ground. As the apple falls, its gravity actually pulls Earth up a very small distance. But Earth moves only the tiniest amount because Earth s pull is so much greater than that of the apple.
Distance and Gravity As objects move closer together, their pull on each other grows stronger. As objects move farther apart, their pull on each other weakens.
Gravity Think of a spacecraft traveling toward another planet. As the spacecraft moves away from Earth, Earth s pull on it decreases. As the spacecraft moves closer to the other planet, that planet s pull on the spacecraft increases.
