Air resistance

What is Air Resistance

• The force of water

• The force that opposes the motion of objects falling through the Earth's atmosphere

• A vacuum

• Terminal Velocity

If a bowling ball and a feather fell in a vacuum, which would hit the ground first

• They would hit at the same time

• The feather

• The bowling ball

• Neither

What causes objects to fall slowly through the air

• Weight

• Surface area

• The color

• Mass

What is Pressure

• A headache

• Something we are all under

• The amount of force acting on a unit of area

• Terminal velocity

What are the 2 ways you can change pressure

• Change the surface area or Change the amount of Force

• Change your attitude and your mind

• Change the temperature and the weather

• Change your shoes and socks

What is the formula for Pressure

• Force divided by area

• Area divided by force

• E equals MC squared

• Y=MX+B

What is air pressure

• Gravity

• The force of air molecules that are pulled toward Earth's center by gravity

• Terminal Velocity

• Bernoulli's Principle

What is Bernoulli's Principle

• Airplanes need an angle of attack

• Lift is the key

• When the speed of a fluid increases, the pressure it exerts decreases

• Gravity is too strong

In order for an airplane to fly the pressure under the wing must be ______________, than the pressure above the wing.

• Greater

• Lower

• Equal

• It doesn't matter. It's going to crash anyways

Why are wings on airplanes curved at the top?

• To make the air go faster over the top of the wing. This lowers the amount of pressure on the wing.

• To make the pressure on top of the wing greater

• To make it look cool

• That was the only model they had
