Forces and fluids

these are the three factors affecting drag force except,

• Size and shape of the object.

• Speed the object is traveling

• Density of fluid through which the object moves.

• Volume and mass of the object.

A force that opposes the motion of an object through a fluid is __________ force.

As you climb up a mountain, the air pressure ___________

What is the equation for pressure?

• Pressure = Force / Surface area
• Pressure = Force x Surface area
• Pressure = Force + Surface area
• I have a 6 foot squirrel named Antney

You can change density of an object by changing the object’s volume.

• True

• False

If you poured the fluids below into a container, which would sink to the bottom?

• water with a density of 1.0 g/cm3

• vegetable oil with a density of 0.91 g/cm3

• honey with a density of 1.36 g/cm3

• air with a density of 0.00013 g/cm3

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

The upward force exerted by a fluid on a submerged object.

• gravity
• anti-gravity
• buoyant force
• lift

This principle says that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid.

• Newton's Principle

• Bernoulli's Principle

• Archimedes' Principle

• Pascal's Principle

Which box has a higher density?  

• Box A
• Box B
• cannot be determined
• they are the same
