Structure and Properties of Matter
What is an atom?
A basic building block of matter.
What is chemical energy?
Energy that's stored inside the bonds of molecules.
What is Newton's First Law?
An object that's at rest stays at rest.
What is a reflection?
Reflection is the process of bouncing back
What do we call the flow of electricity through a wire?
Electricity
What is conductivity?
How easily something let's heat or electricity move through it
What is potential energy?
An object that has energy because of its position.
When two equal forces act on an object in opposite directions, the net force is this
<- 20 ... 20 ->
Zero
What is refraction?
Is the bending of a wave as it passes from one substance into another.
What is the name of the force that pulls objects toward Earth?
Gravity
Anything that has mass and takes up space.
What is energy transformation?
Energy changes from one to form to another.
What is gravity?
The force that pulls all objects toward the center of the Earth.
What is diffraction?
the bending and spreading of waves when they encounter an obstacle, pass through a narrow slit, or pass by an edge.
True or False: There is absolutely zero gravity on the Moon.
False
The mass per unit volume of a substance.
What is the law of conservation of energy?
Energy can never disappear, and it can't be made from anything.
What is Joule (J)?
This is the standard unit used to measure Work.
What is amplitude?
The maximum distance a wave moves from its rest (middle) position
Is lightning a form of static electricity or a battery-powered current?
Lightning is a form of static electricity.
What is a physical change?
A change in form or appearance of matter without a chemical effect.
What is kinetic energy?
Is an object that has energy because its moving.
What is Newton's Third Law?
For every action, there is an equal and opposite reaction.
What is a Wavelength?
The distance between one point on a wave and the exact same point on the next wave.
If you take the North pole of one magnet and put it near the North pole of another, will they stick together or push away?
They will push away.
