What is volume
Amount of space matter occupies
An object that sinks will displace _______ liquid than an object that floats.
more
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No! The mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.
What is the units for volume
cm^3
weight of object is also known as
gravitational force
What is weight
measures the amount of Gravitational force acting on an object
What is displaced water?
A floating object is put into a liquid, and you watch the water level rise because of this. This rise in water level is known as displacement in Archimedes formula?
What is the density of pure water?
1.0 g/mL
what is the units for grams
g
the weight of a displaced liquid is also known as
the buoyant force.
What is a graduated cylinder
the tool used to measure liquid volume
the buoyant force on an object in a liquid is 100 N. What is the weight of the volume of water it displaced?
also 100 N.
How does a decrease in volume of an object affect the density of the object?
Density is how tightly packed atoms in a substance are. If you make the substance smaller, but don't change the amount of atoms, the atoms will be tightly packed.
What is liquid volume
mL
Does a floating object have [balanced/unbalanced] forces?
balanced
What is the amount of matter in an object
define mass
an object sinks when it displaces a volume of water that has a weight _______ the object's weight
less than
Item has a density of 2.5g/cm^3. Will it sink or float in water?
sink
hat is g/mL or g/cm^3
Density units
An object sinking with a changing speed has a [balanced/unbalanced] force?
unbalanced force
What is density
the amount of matter in a given volume
What is the gravitational force on a suspended object that displaces 60 N of water?
60 N
A pencil is floating in liquid A. Another pencil (of the same volume and mass) has sunk in liquid B. Use the terms density to make a comparison between liquid B and A.
Liquid B must be less dense than liquid A.
What is density or g/ml or g/cm^3?
Mass per volume
Which object has a greater buoyant force? A feather floating on the surface of a beaker OR a 50NT coin that has sunk in the beaker.
the 50 NT coin because it displaced more water by being fully submerged in the beaker.
