CAIE考试局ALEVEL物理PAPER 2公式总结

距离ALevel物理（9702）的paper 2考试还剩两天！大家准备的怎么样？今天特意为大家分享As部分务必掌握的公式，相信背过并熟练掌握这些公式，对我们的考试一定有很大帮助。

Force and motion力和运动 

velocity, v=Δs/Δt

acceleration, a=Δv/Δt

v=u+at

s=ut+1/2 at2

v2=u2+2as

s=(u+v)t/2

resultant force, F=ma

weight, W=mg

torque of a couple=force×perpendicular distance between forces

work done, W=Fscosθ (θ is the angle between F and s)

gravitational potential energy, GPE=mgh

kinetic energy, KE=1/2 mv2

internal energy, U=∑PE+∑KE

power, P=W/t=Fv

momentum, p=mv

resultant force, F=∆p/∆t

conservation of momentum,
