137 Terms
vector
A quantity that has magnitude and direction
scalar
A physical quantity that has magnitude only.
rate
a measure, quantity, or frequency, typically one measured against some other quantity or measure.
displacement
Distance and direction of an object's change in position from the starting point.
acceleration
The rate at which velocity changes
average speed
velocity
g= (-9.80 m/s2)
acceleration due to gravity
components
items that become part of the final product
magnitude
size, amount, or numerical value
direction
the path that a moving object follows
free fall
the motion of a falling object when the only force acting on it is gravity
projectile motion
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
range
the difference between the highest and lowest scores in a distribution
trajectory
the curved path of an object thrown into space
Newton's First Law - Law of Inertia
An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force.
Newton's Second Law - Net Force Law
the acceleration of an object is inversely proportional to its mass and directly proportional to the net force acting on it
Newton's Third Law - Action/Reaction Law
For every action there is an equal and opposite reaction
force
A push or a pull
mass
the amount of matter in an object
inertia (identified with mass)
An object with more mass has more inertia, meaning it is harder to start moving, stop moving, or change direction.
net (total) force
The sum of all forces acting on an object
friction
A force that opposes motion between two surfaces that are in contact
normal force
the force perpendicular to a surface that prevents an object from falling through the surface
tension
stress that occurs when forces act to stretch an object
weight
the force of gravity on an object
applied force
a force which is applied to an object by a person or another object
momentum
The product of an object's mass and velocity
impulse
change in momentum
law of conservation of momentum
The rule that in the absence of outside forces the total momentum of objects that interact does not change.
elastic
describes demand that is very sensitive to a change in price
inelastic
Describes demand that is not very sensitive to a change in price
work
Force exerted on an object that causes it to move
power
the rate at which work is done
energy
The ability to do work or cause change
kinetic energy
energy of motion
potential energy
stored energy
total mechanical energy
the sum of kinetic and potential energy
work-energy theorem
The work done on an object equals the change in kinetic energy of the object
law of conservation of energy
Energy cannot be created or destroyed
absolute zero
The temperature at which no more energy can be removed from matter
boiling
The temperature at which a liquid changes to a gas
calorie
Amount of energy needed to raise temperature 1 gram of water 1 degree C
condensation
The change of state from a gas to a liquid
conduction
The direct transfer of heat from one substance to another substance that it is touching.
convection
The transfer of heat by the movement of a fluid
freezing
The change of state from a liquid to a solid
heat
The energy transferred between objects that are at different temperatures
latent heat
heat absorbed or radiated during a change of phase at a constant temperature and pressure
melting
The change in state from a solid to a liquid
radiation
Energy that is radiated or transmitted in the form of rays or waves or particles.
specific heat capacity
the energy required to raise the temperature of one gram of a substance by one degree Celsius
temperature
A measure of how hot or cold something is.
thermal contact
state of two or more objects or substances in contact such that heat can flow from one to the other
thermal equilibrium
The state of two or more objects or substances in thermal contact when they have reached a common temperature
basic law of electrostatics
opposite charges attract, like charges repel
law of conservation of charge
states that charge can be transferred from one object to another but cannot be created or destroyed
charging by friction
two objects rub together and one becomes positively charged and the other becomes negatively charged
charging by induction
the rearrangement of electrons on a neutral object caused by a nearby charged object
charging by contact
the process of transferring charge by touching or rubbing
Coulomb's law
electric force between charged objects depends on the distance between the objects and the magnitude of the charges.
polar
Molecule with partial charges. Mixes with water.
nonpolar
No partial charges. Do not mix with water.
conductor
A material that allows heat and electricity to pass through it.
insulator
A material that does not conduct heat well
grounding
the transfer of excess charge through a conductor to Earth
electric field
a field of force surrounding a charged particle
electric potential difference (voltage)
The ratio of the change in electric potential energy to the charge of an object in an electric field. It is a scalar quantity.
electric potential energy
Energy a charge has due to its location in an electric field
basic law of magnetism
Opposite poles attract, like poles repel
electromagnet
a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil
permanent magnet
A magnet made of material that keeps its magnetism
temporary magnet
a magnet made from a material that easily loses its magnetism
pole
a place on a magnet where magnetism is strongest
dipole
created by equal but opposite charges that are separated by a short distance
magnetic field
The area of magnetic force around a magnet
electric current
The continuous flow of electric charges through a material
closed circuit
a complete circuit through which electricity flows
open circuit
an incomplete electrical circuit in which no current flows
resistance
in psychoanalysis, the blocking from consciousness of anxiety-laden material
Ohm's law
the current in a circuit equals the voltage difference divided by the resistance
series circuit
A circuit in which all parts are connected end to end to provide a single path of current.
parallel circuit
A circuit that contains more than one path for current flow.
equivalent / effective resistance
direct current
an electric current that flows in one direction steadily
alternating current
A flow of electric charge that regularly reverses its direction.
transverse wave
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
longitudinal wave
