TRUE or FALSE Physical properties, like density, does not depend on how much of the substance you have.
TRUE! Physical properties DOES NOT depend on how much of the substance you have – if it is the same substance it should have the same properties!

A force is defined as a ________ or a _________ of an object.
A force is defined as a PUSH or a PULL of an object.

A process for experimentation that is used to explore observations and answer questions
What is the Scientific Method?

Long wavelengths have _________ energy and _______ frequency.
Long wavelengths have LOW energy and LOW frequency.
Short wavelengths have HIGH energy and HIGH frequency.

Adding or removing heat can change the ____________ and/ or the _________ of the object or matter.
Adding or removing heat can change the TEMPERATURE and/or the STATE OF MATTER of the object.

What is the Law of Conservation of Energy?
Energy cannot be created or destroyed but only transformed from one form to another.
200
A melting ice cube is an example of what type of change?
PHYSICAL CHANGE! Phase changes are physical changes- NO new matter is formed.

When finding net force....if the forces are acting in the same direction on the object, ________ the forces together. If the forces are acting in the opposite direction on the object, _________ the forces.
When finding net force....if the forces are acting in the same direction on the object, ADD the forces together. If the forces are acting in the opposite direction on the object, SUBTRACT the forces.

This happens when one scientist runs multiple trials of the same experiment.
What is Repetition?

Light waves travel the fastest in a _______________.
Light waves travel the fastest in a VACUUM. (No matter present)
300
When heat is transferred between two objects through direct touch.
CONDUCTION

Eating food is what type of energy transformation?
Chemical Energy to Mechanical Energy
300
The smallest unit of matter is called _______. And in the nucleus are ______ and ________.
The smallest unit of matter is called an ATOM. And in the nucleus are PROTONS and NEUTRONS.
Electrons are found in the cloud or shells on the outside of the nucleus!
300
If the distance between two objects increases the gravitational pull ________; if the mass increases the gravitational pull _____________.
If the distance between two objects increases the gravitational pull between the objects DECREASES; If the mass increases the gravitational pull also INCREASES.
300
This is when multiple scientists run the same experiment to check the validity of the results.
What is Replication?
400
Sound waves travel the fastest in _________ and the slowest in _________ types of medium.
Sound waves travel the fastest in SOLIDS and the slowest in GASES types of medium.
Remember SOUND waves MUST have a medium to travel!
400
When heat is transferred between two objects when there is no matter needed.
RADIATION

Potential Energy can depend on ___________ and ____________ of an object.
Potential Energy can depend on HEIGHT (gravitational potential) and SHAPE (elastic potential) of an object.
400
If you go to the moon your __________ will change, but your ________ mass will remain the same.
If you go to the moon your WEIGHT will change, (because of the gravitational difference) but your MASS will remain the same.
400
The speed of an object depends on the ___________ traveled and the _________ it takes to travel.
The speed of an object depends on the DISTANCE traveled and the TIME it takes to travel.
400
Information that is acquired by observation or experimentation
What is Empirical Evidence?

What is this an example of- when light changes direction when it goes through a different medium
Refraction- changing direction of light wave when it goes through a matter of different density.
500
This type of heat transfer can only occur in a fluid (liquid or gas). Warmer matter moves up and cooler matter sinks forming currents.
CONVECTION

The periodic table is organized by the ____________ number which is also the number of __________ in the nucleus of an atom.
Ther periodic table is organized by the ATOMIC number which is also the number of PROTONS in the nucleus of an atom.
Remember GROUPS are VERTICAL COLUMNS (18) and the PERIODS are HORIZONTAL ROWS (7).
