Density
Density equals
Mass/Volume
This part of a circuit provides a path for a current of electrons to travel along.
Opposite poles ________________.
Attract
Phase change from gas to liquid.
A rate in change of position in a given direction is known as...
Velocity
Pumice is a special type of rock that floats in water. Why does it do this?
Density is less than that of water.
A neutrally charged object looses electrons. What is the charge on that object now?
Positive
These subatomic particles travel through wire to light circuits.
Electrons.
Kinetic energy is the energy of motion and depends on these two things.
A change in speed or velocity is...
Acceleration
If a person has a mass of 51000g and a volume of 59800ml, what is the density of that person?
0.85g/ml
In this type of circuit, there is only one path for electrons to follow.
Series Circuit
This type of magnet can be turned on and off, and will increase in strength if the number of coils are increased.
Electromagnet
On a piece of paper, draw a particle diagram for a sample of matter in the solid state.
-
Explain the difference between displacement and distance traveled.
-
Explain why some materials like wood float in water but other materials sink.
Densities less than 1g/ml float while densities greater than 1g/ml sink.
You rub a balloon on your hair and the hairs stand up on end after you take the balloon away. Why?
They have the same charge and opposite charges repel.
When iron filings are sprinkled around a magnet, they line up along this...
Magnetic field
Explain the difference between kinetic energy and potential energy.
KE is energy of motion and PE is energy stored in something.
How do we calculate speed or velocity?
S=d/t
If a sphere with a volume of 35ml and a density of 4.3g/ml, what is the mass of the sphere
150.5g
Explain the difference between series and parallel circuits.
Series has only 1 path for electrons while parallel has multiple paths.
This special instrument can be used to tell if something has an electrical charge. We made them in a lab.
Electroscope
What is temperature? Explain in scientific terms.
The average KE of the particles in a sample of a material.
This property is a resistance to a change in motion and depends on mass.
Inertia
