Only one requires air molecules to generate lift.
False, a projectile is simply something that flies through the air irrespective of its shape. A football is a projectile. footballs are pointed though. Think: NERF bullets.
example of fluid friction are air resistance or drag because an object moving through air actually collides with miniature particles, specially dust particles .
true
That is a true statement.
False. liquid water in air forms precipitation
It's a high-pressure zone with rising air. true or false
true
False...
False, air pressure goes down as altitude increases. Air acts like water in the sense that they are both fluids. If you are on the surface of the earth you are in the bottom of the fluid just like water the pressure is higher on the bottom. So when you increase altitude you are reaching the top of the fluid therefore decreasing pressure.
Mass certainly affects the gravitational attraction between objects; air resistance doesn't.
