100
An electric field surrounds this subatomic particle
What is an electron?
100
a core of a magnet is placed inside of the coil of a wire
What is an electromagnet ?
100
Identify the TRUE statement ... A. a hypothesis becomes a law if supported by experiments B. a hypothesis is the truth if 1 experiment supports it C. a hypothesis is not true even if one experiment does not support it D. a hypothesis might be true even if many experiments do not support it
What is "D" ?
100
the theory describing the motion of particles in all 4 phases of matter
What is the kinetic molecular theory?
200
A material that is a poor conductor of electricity
What is an insulator?
200
this flow is created by a closed loop of wire wrapped around a magnet
What is an electric current ?
200
Identify the following laws ... a. an object will stay at rest or continue to move unless acted on by an outside force b. increasing mass increases this force, while increasing distance decreases this force - Law that defines this c. the relationship between force, mass and acceleration d. for every action force, there is a reaction force that is equal in strength and opposite in direction
What is a. 1ST LAW OF MOTION/INERTIA, b. LAW OF UNIVERSAL GRAVITATION/GRAVITY, c. 2ND LAW OF MOTION/FORCE, d. 3RD LAW OF MOTION
200
these two forces act on all objects within a fluid
What is gravitational force and buoyant force ?
200
the 3 ways to describe the transfer of thermal energy or HEAT 1. transfer between solids 2. transfer between fluids (gas and liquids) 3. transfer that does not require matter to be present
What is 1. conduction, 2. convection and 3. radiation
300
the movement of negative charges between objects that are touching
What is conduction?
300
the energy transformation that occurs within a magnetic generator
What is mechanical energy to electrical energy ?
300
IDENTIFY THE FOLLOWING LAWS IN PHYSICAL SCIENCE a. in any energy transformation - energy is never lost or gained - it is converted from one form to another b. in any physical or chemical change - matter cannot be destroyed; the total matter before the change will equal the total matter after the change c. in any collision of 2 or more objects, the product of the mass and velocity will remain the same before and after the collision - the mass and velocity are not lost - they are transfered from one object to another
What is the LAW OF CONSERVATION ...a. LOC of ENERGY, b. LOC of MASS, c. LOC of MOMENTUM
300
this property of matter is proportional to the mass of an object and subject to the force of gravity
What is weiGht?
300
a measure of the average kinetic energy between particles
What is temperature ?
400
process by which negative charges become concentrated at one end of an object - then the other end becomes positively charged
What is polarization?
400
the location on a magnet where the magnetic field is the strongest
Where is the magnetic poles ?
400
the relationship or equation between momentum (p) and 2 key variables
What is p=mv
400
this force opposes motion; sub-catagories include fluid static, sliding, and rolling
What is friction ?
400
the form of energy derived from the center of an atom - specific cases include fusion and fission
What is nuclear energy?
500
the movement of negative charges between objects that are not touching
What is induction?
500
3 ferromagnetic elements in order of magnetic strength
What is Fe, Co, Ni ?
500
the two variables that are defined in the Law of Universal Gravitation
What is mass and distance ?
500
a property of matter which describes the product of the velocity and mass of an object
What is momentum?
500
process where dry ice increases its thermal energy between particles and changes from a solid into gas without going through the liquid phase
What is sublimation?
