True. Air is classified as a fluid because it can flow and take the shape of its container, similar to liquids. Fluids are characterized by their ability to move and deform, and air exhibits these properties as a gas.
true
true
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.
A true statement about projectiles is that they follow a curved trajectory known as a parabolic path when launched into the air, influenced primarily by gravity and initial velocity. The horizontal motion of a projectile is constant, while its vertical motion is affected by acceleration due to gravity. This means that, neglecting air resistance, the horizontal and vertical motions are independent of each other.
true
That is a true statement.
It's a high-pressure zone with rising air. true or false
true
Mass certainly affects the gravitational attraction between objects; air resistance doesn't.
false
true
true?
True. The dew point is the temperature at which air reaches saturation and water vapor in the air begins to condense into liquid water on surfaces.
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.
No atmospheric pressure
