📝d = vt

📝d = at²

📝d = (vf + vi/2) ×t

📝d = 5t² (for distance in 'n' seconds) 

📝d = 5(2tn - 1) (for distance in 'nth' second) 

📝d = 1/2 mv²/F

📝d = vit + 5t²

📝d = v × underroot 2H/g

📝d = vt = x°wt = x°2pi/T × t = x°2pift

v = underroot 2as

v = underroot gr (speed at highest point in a verticle circle)

v = underroot 5gr (speed at lowest point in a verticle circle) 

📝v² = 2FS/m

📝v² = 2E/m

📝v² = 2Ve/m
