Study Notes

Current

Formula: Current = charge/time (I = q/t)
Units: Amperes (A)

Work

Formula: Work = Force x distance (W = F x d)
Units: Joules (J)

Power (Work)

Formula: Power = Work/time (P = W/t)
Units: Watts (W)

Momentum

Formula: Momentum = mass x velocity (p = mv)
Units: kg m/s

Net Force

Formula: F_net = mass x acceleration or F_net = F1 + F2 + ...

Average Velocity

Formula: Average Velocity = change in position/time (V_avg = ΔX/t)

Potential Energy

Formula: Potential Energy = mass x gravity x height (PE = mgh)
Units: Joules (J)

Acceleration

Formula: Acceleration = change in velocity/time (a = (V_f - V_i)/t)

Kinetic Energy

Formula: Kinetic Energy = 1/2 x mass x velocity^2 (KE = 1/2 mv^2)
Units: Joules (J)

Weight

Formula: Weight = mass x gravity (W = mg)

Electric Power

Formula: Electric Power = current x voltage (P = IV)
Units: Watts (W)

Force of Gravity

Formula: Gravitational Force = G(m1m2)/distance^2 (F_g = G(m1m2)/d^2)

Kinematic Equations

Equation without distance: Final velocity = initial velocity + acceleration x time (V_f = a t + V_i)
Equation without time: Final velocity squared = initial velocity squared + 2 x acceleration x change in position (V_f^2 = V_i^2 + 2aΔX)
Equation without acceleration: Change in position = 1/2(initial velocity + final velocity) x time (ΔX = 1/2(V_i + V_f)t)
Equation without final velocity: Change in position = initial velocity x time + 1/2 x acceleration x time^2 (ΔX = V_i t + 1/2 at^2)

Law of Conservation of Energy

Equation: Initial potential energy + initial kinetic energy = final potential energy + final kinetic energy (mgh_i + 1/2m v_i^2 = mgh_f + 1/2mv_f^2)

Trigonometric Functions

Sine: sin(θ) = opposite/hypotenuse
Cosine: cos(θ) = adjacent/hypotenuse
Tangent: tan(θ) = opposite/adjacent

Law of Conservation of Momentum

Formula: (mass1 x initial velocity1) + (mass2 x initial velocity2) = (mass1 x final velocity1) + (mass2 x final velocity2)

Ohm's Law

Formula: Voltage = current x resistance (V = IR)

Coulomb's Law

Formula: Electrostatic Force = (constant x charge1 x charge2)/distance^2 (F = kq1q2/d^2)

Resistance in Circuits

Parallel Resistance: 1/Equivalent Resistance = sum of the inverses of resistors (1/R_eq = 1/R1 + 1/R2 + ...)
Series Resistance: Equivalent Resistance = sum of resistors (R_eq = R1 + R2 + ...)

Constants

Coulomb's Constant: 8.99 x 10^9 N m²/C²
Gravitational Constant: 6.67 x 10^-11 N m²/kg²
