force and motion
change in position of an object over time.
what is motion?
energy of motion
what is kinetic energy?
when light passes through an object.
what is transmission?
the attraction and repulsive forces between two poles
what is magnetic forces?
the energy transffered between two objects of different temp
what is heat?
a push or pull on an object with another object.
what is force?
when energy is stored
what is potential energy?
when light occurs and an object doesnt reflect or transmit the light.
what is absorption?
the north and south poles
what is the two poles of a magnet called?
is the messurement of how many joules of heat are required to change the temp
what is specific heat?
s=d/t
what is the equation for speed?
energy that is tansferred by direct contact
what is conduction?
the angle of incidence = the angle of reflection
what is the law of reflection?
wrap iron or steel around
how do you make a magnet stronger?
buring wood
what is an example of heat transfer?
weight=ma
what is the equation for gravity?
mass x velocity2/2
what is the equation for K.E?
two or more waves overlap and combine to form a new wave
what is wave interfernce?
atom with a positive charge
what is a proton?
transfer of thermal objects when touching
what is conduction?
this law says that and object at rest stays at rest and an object in motion stays in motion unless it gets an extrenal force.
what is newtons first law of motion?
streaching a rubber band.
the appartent bending of waves around small obstacles
what is diffraction of light?
rate of flow or charged particles
what is electric current?
materials that conducts or transfers thermal energy well
what is a thermal condoctor?
