Acids, Bases Solutions
suspension
a mixture in which particles can be seen and easily separated by settling or filtration
INERTIA
the tendency of an object to resist a change in motion
Force
A push or a pull
Work
Occurs when a force moves an object over a distance in the same direction as the force. The formula for work is: Force x Distance
kinetic energy
the energy an object has due to its motion
concentrated solution
a mixture that has a lot of solute dissolved in it
VELOCITY
a term used to describe an object's speed AND direction
mass
The amount of matter in an object.
The measurement of inertia in an object.
Mechanical Advantage
A numerical value given to a machine which tells how many times the machine multiplies a force.
potential energy
stored energy that results from the position or shape of an object
solubility
a measure of how much solute can dissolve in a given solvent at a given temperature
Newton's 1st Law of Motion
An object at rest tends to stay at rest and an object in motion remains in motion unless acted on by an unbalanced force.
weight
the measurement of the pull of gravity on an object.
Ideal Mechanical Advantage (IMA)
Deals with distances and does not account for friction. IMA: Distance Input/Distance Output or IMA: Length Input/Length Output. (NO UNIT)
gravitational potential energy
potential energy that depends upon an object's height
acid
a substance that tastes sour, reacts with metals and carbonates, and turns blue litmus paper red
Newton's 2nd Law of Motion
The acceleration of an object depends on the mass of the object and the force applied. A math equation that represents this law is: force = mass x acceleration (F=m x a)
Frictional Force
the resistance when two objects slide past one another
Which number is always larger; AMA or IMA?
IMA
matter
anything that has mass and takes up space
supersaturated solution
a mixture that has more dissolved solute than is predicted by its solubility at a given temperature
Newton's 3rd Law of Motion
Every action has an equal and opposite reaction.
unbalanced force
Unequal forces acting on an object, cause motion
Work Output
The work that is done by the MACHINE
law of conservation of energy
Energy cannot be created or destroyed
