初速度为0的公式:s=at^2/2,v=at
1)Ts内位移比:1T=t,2T=2t,3T=3t.nT=nt
S1=at^2/2,S2=a(2t)^2/2,S3=a(3t)^2/2,.Sn=a(nt)^2/2
S1:S2:S3:...:Sn=1^2:2^2:3^2:.:n^2
2)Ts末速度比:v1=at,v2=a(2t),v3=a(3t).vn=a(nt)
v1:v2:v3:...:vn=1:2:3:.:n
3)相同位移间隔时间比:
S1=a(t1)^2/2,S2=a(t2)^2/2,S3=a(t3)^2/22.Sn=a(tn)^2/2
由于S1:S2=1:2,得出(t1)^2:(t2)^2=1:2,即t1:t2=1:√2
S1:S3=1:3,得出(t1)^2:(t3)^2=1:3,即t1:t3=1:√3
S1:Sn=1:n,得出(t1)^2:(tn)^2=1:n,即t1:t3=1:√n
t1:t2:t3:.:tn=1:√2:√3:...:√n
4)根据公式(v)^2-(v0)^2=2as,其中v0=0,v=√2as
v1=√2aS1,v2=√2aS2,v3=√2aS3.vn=√2aSn
式中S1:S2:S3:...:Sn=1:2:3:...:n
所以V1:V2:V3:.:Vn=1:√2:√3:...:√n
