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.
