This document defines mass and weight, discusses gravity as the downward force that causes objects to fall when dropped, explains that gravity pulls on all objects at 9.81m/s^2, and notes that air resistance can affect whether objects fall at the same rate or not.

this specific thing a force?

4. Gravity
• Gravity is a force that pulls things
downward.
• Mass- Amount of matter inside an object.
• Weight- the force of gravity pulling down
on an object.
• Gravity pulls every object at a speed of
9.81m/s2 or 32.1 ft/s

• Air resistance- determines if objects fall at
the same rate or not.
