Key Measurements
The amount of in an object
What is matter
The ability to in water, air, or other fluids.
float
if it is negatively buoyant will it sink or float
will sink
D = M / V
Formula for density
what is regularly shaped
sides are smooth; can find volume using ruler
The measurment from
end to end
Calculated using the formula:
density = mass ➗volume.
if it is neutrally buoyant will it float or rise
will rise
Density of water
what is irregularly shaped
sides are uneven; to find volume use water displacement
The amount of
matter in a given space
Units for density
g/cm3 or g/mL
If it is positively buoyant will it float or sink
float
Object floats in water
if density of object is less than dense than water
if it is neutrally buoyant will it sink or hover
hover
The downward force of an object because of its weight is the
Gravitatinal Force
Volume of a solid irregularly-shaped object is measured using
water displacement,
What is density
the amount of matter in a given space, formula used, Density=mass/volume, units cm, meters
Triple beam balance
instrument used to measure mass
To calculate the density of a substance, you must know 2 things about the substance. What are they?
Volume and Mass
The upward force of a fluid
on an object is the buoyant force
What is Mass
The amount of matter in an object is measured in grams using a triple beam balance or digital scale (kg, mm).
What is length
Measure from one end to the other using a ruler and record the measurement in meters, centimeters, or millimeters.
what is Meniscus
The curved upper surface of a liquid in a tube
grams/mL is the unit for ____________?
density
