• Aerodynamics

• buoyancy

• pressure

• hydraulics

One day after swimming lessons Melanie decides to stay at the pool for open swimming. She relaxes by floating on her back in the cool water. She feels weightless as the water supports her. What allows Melanie to float on the water instead of sink?

• Pascals

• buoyancy

• pressure

• volume

Bernoulli's principle explains why ___________.

• airplanes fly

• boats float

• pistons work

• ice melts

Which of the following would be used to measure pressure?

• Grams

• Newtons

• Pascals

• Kilograms

Which of the following uses Pascal's principle?

• Airplanes

• Hydraulics and pressure

• Boats

• Snowboards

Which of the following uses Bernoulli's principle?

• Airplane wings

• Pistons

• Boats

• Snowboards

What is the upward force in a fluid?

• Pressure

• buoyancy

• kinetic theory

• Diffusion

Bernoulli's principle states that

• pressure is transmitted equally through a fluid.

• pressure increases as temperature decreases.

• buoyant force equals weight of fluid displaced.

• pressure in a fluid decreases as speed of the fluid increases.

As part of a physics demonstration, Mr. Taylor suspends two ping pong balls next to each other so that they have a small space between them. He then turns on a hairdryer and has it blow air in the space between the two ping pong balls. Which of the following should happen?

• the two balls do not move

• the two balls move upward

• the two balls move further apart

• the two balls move closer together

A large truck passes a car on the highway. According to Bernoulli's principle, which of the following should occur?

• Pressure decreases between the vehicles, so the car and truck move slightly apart.

• Pressure decreases between the vehicles, so the car and truck move slightly together.

• Pressure increases between the vehicles, so the car and truck move slightly apart.

• Pressure increases between the vehicles, so the car and truck move slightly together.
