Motion, Energy, Work, Power, Circuits Review

Front

Conductor

Back

Material that transfers energy easily. Ex. copper wire.

Front

Insulator

Back

Material that resists energy transfer. Ex. rubber.

Front

Series Circuits

Back

Current is constant everywhere! Vtotal = V1 + V2 + V3... Rtotal = R1 + R2 + R3...

Front

Parallel Circuit

Back

The voltage is the same everywhere.

Front

Total Current in Parallel Circuit

Back

Itotal = I1 + I2 + I3 + ···

Front

Total Resistance in Parallel Circuit

Back

(Rtotal) = (R1^-1 + R2^-1 + R3^-1 ...)^ -1

Front

Displacement (∆x)

Back

The change in an object's position. [∆ is said 'change in' and means final - initial]

Front

Equation for Displacement

Back

∆x = x2 - x1; ∆x = final position - initial position

Front

Velocity

Back

Displacement/time; Units are m/s; vector

Speed

Back

Distance/time; Units are m/s; scalar
