Review #3 Physics S2 Final

Front

What is the definition of density?

Back

Density is the amount of mass per unit of volume.

Front

Are rogue 'Freak' waves caused exclusively by stronger winds?

Back

False. Rogue waves can be caused by a combination of factors, not just stronger winds.

Front

What quantity is divided by surface area to calculate pressure?

Back

Force.

Front

Why do snowshoes make it easier to walk on snow?

Back

Because the larger the area over which force is distributed, the less pressure is exerted.

Front

What principle explains why smoke rises from a chimney?

Back

Bernoulli's Principle.

Front

What is pressure?

Back

Pressure is defined as force per unit area.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

Front

What does Bernoulli's Principle state?

Back

Bernoulli's Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.

Front

What is Pascal's Principle?

Back

Pascal's Principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid.

Front

How does increasing the area of contact affect pressure?

Back

Increasing the area of contact decreases the pressure exerted on a surface.
