Forces in Fluid Quiz

Mr. Lewis’s 8th Grade Science

- Decrease the person’s weight on the snow.
- Increase the area over which the person’s weight is distributed
- Increase the pressure on the snow
- Increase the buoyancy of the person

- Bernoulli
- Pascal
- Pound
- meter

- Balanced pressure
- Gravitational pressure
- Fluid pressure
- Constant pressure

- Human skin is extremely strong.
- Earth’s gravity cancels out air pressure
- Pressure inside your body balances the air pressure outside your body.
- Inertia changes the pressure before it comes into contact with you.

- Velocity increases
- Elevation increases
- Acceleration decreases
- Gravity increases

- Depth increases
- Gravity increases
- Force decreases
- Acceleration increases

- Solids
- Fluids
- Powders
- Metals

- A hydraulic car lift
- The flight of an airplane
- A speedboat’s bottom slapping against the waves.
- The buoyancy shown by ducks and other waterfowl

- Bernoulli’s principle
- Archimedes’ principle
- Pascal’s principle
- Newton’s first law of motion

- Decrease pressure
- Increase velocity
- Multiply force
