MCAT Physics Equations with Correct Answers (100% Accurate)
Linear Motion, Δx, Vo, a, t Correct Answer Δx=V₀*t+1/2 a*t² Linear Motion, V, Vo, a, x Correct Answer V²=V₀²+2aΔx Linear Motion, Δx, avg. V, t Correct Answer Δx=avgV*t=((V₀+V)/2)*t Law of gravitation Correct Answer F=Gm₁m₂/r², where G is the gravitational constant Torque Correct Answer τ=rFsinθ, where θ=angle between r and F Kinetic friction Correct Answer f=μN, where N=normal force and μ=friction coefficient Centripetal Force Correct Answer F=mv²/r Work Correct Answer W=Fdcosθ, measured in Joules, 1 J=1 N*m Power Correct Answer P=W/t, measured in Watts, 1 watt=1 J/s Momentum Correct Answer p=mv Impulse Correct Answer J=F*t=Δp=mΔv Specific Heat Correct Answer Q=mcΔT; only where there is no phase change. Q= Heat supplied to substance, m= Mass of the substance, c= Specific heat capacity, T= Temperature rise. The smaller the specific heat capacity (c), the LESS energy is required to raise the temperature of that substance by a certain amount! Heat of Transformation Correct Answer Q=mL, where L is the heat required to change phase of 1 kg of substance Pressure Correct Answer P= ρgh; P=F/A, in Pascals, 1 Pa=1 N/m² Thermodynamic Work Correct Answer W=PΔV First Law of Thermodynamics Correct Answer ΔU=Q-W, work done by the system. ΔU=Q+W, work done on the system Density Correct Answer ρ=m/v
