Simple Power Equation + Units
P=Energy/ TIme (Watts)
Units of Power
1 watt= 1 j/s =1 Nm/s= 1 kgm²/s³
Magnification Equation
What does it mean if magnification value is +
image is upright
What does it mean if magnification value is -
image is inverted
what does it mean if the absolute value of magnification is more than 1
the image is magnified
what does it mean if the absolute value of magnification is less than 1
the image is minified
basic force equation
F=m*a
equation for velocity given initial veloc., time, and acceleration
equation for the frequency of an open pipe
fn= waves frequency
n= # of node
v= velocity
L= length

General kinetic energy equation
KE=1/2 m*v²
General potential energy equation
PE=m*g*h
what is the total resistance of resistors in series?
RTotal=R1+R2+R3
what is the total current from a battery through resistors in series?
ITotal=I1=I2=I3
each resistor recieveds the same amount of current
