elastic vs inelastic

inelastic collisions is when the object sticks together.
elastic collisions is when the object bounces off.
an elastic collision i saw in my daily life is  is a ball bouncing.
and an inelastic collision i saw in my daily life is a car crash
when the cars stick together

phase changes

i saw a ice cube melting it is a phase change
because it changes from solid to liquid.
its transition is called melting. heat energy
was added thats why it melted.

too hot too cold

metal is a conductor
light is radiation
plastic is a conductor
they heat up at different rates because their different materials

doppler rador

Doppler radars are far and away the best tool for detecting rainfall around the area . 
They work by sending beams out in a circle pattern around the radar.

interferences

1. the difference between constructive and destructive interference is when the constructive interference is If the two amplitudes have opposite signs, they will subtract to form a combined wave with a lower amplitude. The destructive interference is when a Sound waves with higher amplitudes sound louder than sound waves with lower amplitudes.one of my examples is noise canceling headphones that is a destructive interference. 

standing waves

in todays lab drew the wave then we find the wavelength then we find the frequency then after that we find the speed you find the speed by multiplying the wavelength and the frequency together.
today i learned how to find the frequency and to find the speed of the wave.

no effect

the waves from the telephone because the radio active.
it has no effect because it doesn't bother you.
