force & motion
What was Newton's first law?
An object at rest will stay at rest unless acted on by
an unbalanced force.
What is the difference between decomposition and synthesis
synthesis combines simpler substances into a more complex compound while decomposition breaks a simple compound into simpler substances.
what is matter?
Anything that has mass and takes up space
What is the difference between potential energy and kinetic energy?
potential energy is stored energy based on an object's position or state, while kinetic energy is the energy of actual motion
what do fluids include? Hint there is 2.
Liquids and gasses
True or false
Acceleration is a vector quantity
True
NaCl + AgNO3 → NaNO3 + AgCl
What type of equation is this?
Double replacement
what are the 3 primary states of matter
solid, liquid, and gas
How does the Law of Conservation of Energy show the transfer of energy as a roller coaster drops from its highest point?
Its stored gravitational potential energy is continuously converted into kinetic energy, keeping the total mechanical energy constant
what is the formula for pressure?
p = f / a
Name each of Newton's laws in order.
1. For every action, there is an equal and opposite
reaction.
2. An object at rest will stay at rest unless acted on by
an unbalanced force.
3. The acceleration of an object by a force is inversely
proportional to the mass of the object and directly
proportional to the force.

(Red)(Blue)+Green -> (Red)(Green)+Blue
What type of chemical equation is shown?
Single replacement
The three primary states of matter are solid, liquids, and gas. What is the fourth state
plasma
When water boils in a pot on the stove, what are the three methods of heat transfer taking place ?
conduction, convection, and radiation
When the buoyant force on an object is greater than the object's weight, does it sink or float?
Float
If a dog, with an initial velocity of 56 m/s, accelerates at a rate of 15 m/s^2 for 9 seconds, what will its final velocity be?
191 m/s
How can you tell that the equation is combustion
look for a fuel typically a hydrocarbon, which contains Carbon and Hydrogen reacting with O2
When the temperature of a gas at constant pressure increases, what happens to the volume?
it increases
Which fossil fuel provides the U.S. with the most energy.
Petroleum (such as gasoline, diesel, and jet fuel) provides the U.S. with the most energy, accounting for over a third roughly 36%
Water exerts fluid pressure on how many sides of an object
all sides of an object.
give equation for speed
speed=distance/time
Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
What equation is shown?
single replacement
which law said that
"At a constant volume, for a given amount of gas, the pressure is directly proportional to the temperature."
Charles’s Law
Boyle’s Law
Gay-Lussac’s Law
Gay-Lussac’s Law
What are the main advantages and disadvantages of using wind energy as a power source?
Clean, renewable, and increasingly cost-effective source of power that significantly reduces greenhouse gas emissions. Its disadvantages include intermittency of the wind, geographic limitations, and impacts on local wildlife and landscapes.
Who's principle 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?
Archenemies Principle
