1.速度v=s/t; 2.密度ρ=m/v; 3.壓強P=F/s=ρgh;
4.浮力F=G排=ρ液gV排=G(懸浮或漂浮)=F向上-F向下=G-F’ ;
5.杠桿平衡條件:F1L1=F2L2;6.功w=Fs=Gh(克服重力做功)=Pt;7.功率p=W/t=Fv;
8.機械效率η=W有/W總=Gh/Fs=G/nF=G/(G+G動) =fL/Fs(滑輪組水平拉物體克服摩擦力作功);
9.熱量:熱傳遞吸放熱Q=cm△t;燃料完全燃燒Q=mq=Vq;電熱:Q= I2Rt
10.電學(xué)公式:電流:I=U/R=P/U 電阻:R=U/I=U2/P 電壓:U=IR=P/I
電功:W=Pt =UIt =I2Rt=U2t/R 電熱:Q= I2Rt(焦耳定律)=UIt==U2t/R
電功率:P=W/t= UI=I2R=U2/R
