Question | Answer |
FORCE | a push or pull of an object. |
WORK | the force to move an object. |
WAVE | the transfer of energy. |
MEDIUM | the material that a wave can travel. |
CREST | point where wave reaches it highest. |
TROUGH | point where wave is at its lowest. |
LONGITUDINAL WAVE | where waves move back and forth in same direction. |
COMPRESSION | when energy is combined into one and then split up again. |
RAREFACTION | where the energy is spread out opposite of compression. |
TRANSVERSE WAVE | where waves move to the direction or the direction or the direction it travels. |
MECANICAL WAVES | require medium. |
ELECTROMAGNETIC WAVES | vibrations of electromagnetic fields and does not need a medium. |
AMPLITUDE | measure of how far partials in a medium and the amount of energy in a wave. |
WAVE LENGTH | a distance from point to point. |
FREQUENCY | the amount of waves that pass a given amount of time. |
HERTZ | the way frequency is measured in. |
WAVE SPEED | speed waves travel. |
POWER | the rate at which work is done work divided by time. |
HOW DO YOU CALCULATE WAVE LENGTH | wave length divided by frequency |
BRANDON IS STROLLING THROUGH THE SCHOOL AND WHEN HE STOPPED HAD 3789 JOULES OF WORK THAT HE DID AND HE HAD WALKED FOR 2 MIN HOW MUCH FORCE DID HE HAVE? | 31.575 N |
HOW DO YOU CACULATE WORK? | force times distance |
WHAT DOES JOULES STAND FOR | the unit for work |
WHAT DOES NEWTONS STAND FOR | the unit for force |
WHAT NUMBER IS ALWAYS THE BIGEST WHEN CACULATING POWER | work |
WHAT DOES WATTS STAND FOR | the unit for power |
IF BRANDON WALKED 68 METERS AND HAS A FORCE OF 300 NEWTONS OF FORCE WHAT IS THE AMOUNT OF WORK THAT HE IS DOING | 2040 |
