Specific Gravity
A derived, secondary, physical quantity determined by the product of two lengths.
1 kg x 1 m/s^2
Newton
mass / volume
density
When an ice skater lifts her arms up and away from her body while spinning, her angular velocity will
decrease
A measure of how easily a material will stretch when pulled or how well the material will shorten when pushed.
Modulus of Elasticity
Revolutions per second and radians per second is known as what type of speed?
angular speed or angular velocity
kg / m^3 is a unit of
density
M = force x perpendicular distance.
What is M?
Moment
When thinking about pressure, you should think of
snowshoes or a knife
A measure of how hard it is to rotate something with respect to its center of gravity
Mass moment of inertia
The weight of the fluid displaced is equal to
buoyant force
SI base unit of electric current
amp
Volume / Time
Volume flow rate
If an objects specific gravity is greater than one... it will
sink
The ability to resist bending
second moment of area or area moment of inertia
The quantity that represents a measure of how easily a given fluid can flow is known as
viscosity
Nm
We can relate angular velocity and linear velocity if this is known.
radius
You can relate volume flow rate to the velocity in a closed system of pipes if you are given what other variable?
Cross-sectional area of pipe
