Forces in Fluid Quiz

Mr. Lewis’s 8th Grade Science


Snowshoes enable a person to walk on deep snow because the snowshoes
Snowshoes enable a person to walk on deep snow because the snowshoes…

  • 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


A unit of pressure is called a
A unit of pressure is called a … snowshoes…

  • Bernoulli

  • Pascal

  • Pound

  • meter


Air pressure exerted equally on an object from different directions is
Air pressure exerted equally on an object from different directions is …

  • Balanced pressure

  • Gravitational pressure

  • Fluid pressure

  • Constant pressure


Given that the air pressure outside your body is so great why aren t you crushed
Given that the air pressure outside your body is so great, why aren’t you crushed?

  • 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.


Air pressure decreases as
Air pressure decreases as… why aren’t you crushed?

  • Velocity increases

  • Elevation increases

  • Acceleration decreases

  • Gravity increases


Water pressure increases as
Water pressure increases as… why aren’t you crushed?

  • Depth increases

  • Gravity increases

  • Force decreases

  • Acceleration increases
