Waves
what is a wave?
a repeating disturbance that transfers energy through matter and space
What is energy?
ability to do work
whats radiation?
heat transfer by electromagnetic waves
when an object changes it position
whats newtons 1st law?
an object will move at a constant velocity until a net force acts on it.
what is waves transfer energy?
Only energy carried by the wave moves forward. Matter isn't transported.
what is kinetic energy?
energy of motion
Hot air rises, it would be smarter to put your air vents on the floor
define reference
an indicator that orients; the place from where you measure, record, or witness and event
Whats intertia
the tendency of an object to resists a change in motion.
where is the crest in a wave
the peak or highest point
whats potential energy?
stored energy
What is convection?
heat transferred by CURRENT
how far an object has moved
whats newtons 2nd law
a net force acting on an object causes the object to accelerate.
where is the trough in a wave?
the lowest point in the wave
what is solar energy from?
heat transferred by direct contact
whats displacement
distance and direction of an objects change in position; difference from starting to ending point
whats newtons 3rd law
every action
whats wavelength?
the distance from a wave oscillates from its resting position
Whats wind energy?
moving air
Who does hot air rise?
because it is lighter than cool air
whats speed?
the distance a object travels per unit
For newtons 2nd law, what happens if the mass is high?
the greater the mass, the greater the force needed to accelerate it
