Labeled Waves

 Waves are a way in which energy is transferred. You can see the energy moving forward. The difference between transverse and longitudinal is the direction the medium travels in relation to the energy.

What are the parts of the wave???

Know these terms:

• Compression
• Crest
• Amplitude
• Wavelength
• Rest position/equilibrium

Calculating Cost of Electricity

Price for electricity is given in $/kWh.

If you'd like to know the cost you follow this formula:

$ = $/kWh * kW *h

OR

$ = $/kWh * kWh

Notice, since the price is given as an amount per 1 kWh, you need to find the total amount of kWhrs then multiply the price by your kWh.

Specific Heat Capacity

 

Specific heat capacities are SPECIFIC to certain types of substances. If you have something that is changing temperature you have a specific heat capacity measured in J/gºC. However, if something is not changing temperature (freezing/boiling point or on fire) then you have units measured in J/g (or J/mol).

Energy Conservation

 Mechanical Energy = potential + kinetic. 

Objects moving up and down turn their PE-->KE and KE-->PE
