Gravity and upthrust keep the balloon in the air
What is drag
To slow something down in the air
Give an example of a contact force
Friction is the contact force
What decreases friction
Moving slow, lubrication and streamlined shapes

Went to forces the same size act against the will of objects in opposite directions
What is mass
How much stuff something is made up of measured in kilograms
