Algebra Based Physics Flashcards

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
