Use the spaces below to take notes on the key concepts presented in this study. Main idea: Gravity can be defined as the natural force of attraction Earth exerts on objects at or near its surface, which tends to draw these objects toward Earth’s center.

Objects with different mass fall with
the same acceleration

Explored “How do objects fall?”

When an object falls
only under the force of
gravity.

There is none!

The natural force of attraction Earth
exerts on objects at or near its
surface, which tends to draw them
toward Earth’s center.

No air resistance so all objects
fall at the same rate.

A form of friction between a moving
object and air that causes the
object to slow down.

g=9.8 m/s^2

v=(9.8 m/s^2)t

The greater the surface area,
the greater the air resistance.

Greater the speed, the greater
the air resistance.
