ANSWERS SURE A+
✔✔Simple Harmonic Motion - Restoring Force - Pendulum - ✔✔F = restoring force, m =
mass attached to pendulum, g = acceleration due to gravity, θ = angle between
pendulum arm and the vertical. F acts tangential to arc of circle. Max F and a at max θ.
✔✔Simple Harmonic Motion - Potential Energy - Pendulum - ✔✔
✔✔Density - ✔✔Units = kg/m³
✔✔Specific Gravity - ✔✔if >1 will sink, if <1 will float in liquid water. If <1 SG = % of
object that is submerged.
✔✔Pressure - ✔✔Unit = N/m² = Pascal (Pa)
✔✔Fluid (Gauge) Pressure - ✔✔
✔✔Absolute Pressure - ✔✔
✔✔Pascal's Law - ✔✔When a change in pressure is applied to an inclosed fluid, that
pressure change will be transmitted undiminished to every portion of the fluid and to the
walls of the vessel.
✔✔Coulomb's Law - ✔✔Unit = Newtons
✔✔Electric Field (w/Test Charge) - ✔✔Unit = Newtons/Coulomb (or Volts/meter)
✔✔Electric Field (w/Point Charge) - ✔✔Unit = Newtons/Coulomb (or Volts/meter)
✔✔Electric Potential - ✔✔Unit = Volts (Joules/Coulomb). Positive charges move from
high potential to low potential, negative charges move from low potential to high
potential.
✔✔Current - ✔✔Unit = Coulomb (charge/second)
✔✔Ohm's Law - ✔✔
✔✔Electrical Power - ✔✔The amount of power dissipated by a resistor.
✔✔Resistors in Series - ✔✔Vs = V₁ + V₂ + V₃ + etc.
✔✔Resistors in Parallel - ✔✔Vp = V₁ = V₂ = V₃ = etc.
