Matter
this has mass and takes up space.
What is matter?
It can be replenished in a short period of time.
renewable energy.
The amount of force exerted to a given area.
Pressure
Acceleration is a measure of the change in velocity over
time
Dmitri Mendeleev
the scientist to create the first periodic table.
The smallest unit of matter (the basic unit from which all matter is made).
Atom
the two main types of energy.
Potential and Kinetic
p=f/a
the formula of pressure.
means the object is at rest (not moving).
flat, horizontal line
contains chemical formula for carbon dioxide
An element.
the state of matter that molecules are closely packed together and vibrating in place.
Solid
gravitational potential energy depends on.
weight and height.
increases with the depth because of gravity
Water pressure.
(\(F = ma\)): Acceleration depends on the mass of the object and the net force applied.
the second law
always involve the formation of one or more new substances
chemical reaction
If temperature is increasing what happens to molecular motion? Does it increase or decrease?
it increases.
Burning of fossil fuels increased this gas level in the atmosphere.
Carbon dioxide.
states that as the speed of a moving fluid increases, its pressure decreases.
Bernoulli’s Principle
An object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an outside force (like friction).
first law
AgNO3(aq) + NaCl(s) NaNO3(aq)
This is an example of a double replacement.
The state of change is endothermic and changes a gas to a plasma.
ionization
the percentage of our energy comes from renewable energy sources.
10%
states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces.
Archimedes Principle
(Action-Reaction): For every action, there is an equal and opposite reaction.Example: When you jump off a skateboard, the board pushes you forward while your feet push the board backward.
third law
the subatomic particle carries a negative charge and orbits the center of the atom
the electron
