Science:energy And Matter Flashcards
Repeatedly coverts potential energy to kinetic energy and back again
Pendulum
Kinectic energy of all atoms or molecules in a substance
Temperature
Movement of energy from one substance to another
Heat
Gas stored in a gas tank example of _ potential energy
Chemical potential energy
A battery is an example of _ potential energy
Electric potential energy
Waves that vibrate up and down (ripples on a pond)
Transverse waves
Waves that travel through compression (slinky)
- ex: created by vibration
Longitudinal waves
Sound
Measure of a waves displacement from rest position
Distance btwn crests in a wave
Amplitude
Wavelength
Number of times per second the wave cycles
Time btwn wave crests
Position on a wave cycle at a given point in time
Frequency
Period
Phase
Change in wavelength when waves are compressed when an object is close, waves are spread out when object is further away
Ex: ambulance siren
Doppler effect
Color frequency
Red/orange
Blue /violet
Red/orange - low frequency
Blue/ violet- high frequency
Created by the alignment of spinning electrons within a substance
Magnets
