Kinematics formula

V_i=initial velocity

V_ix=initial velocity in the x/horizontal direction| V_ix=Vi cos θ

V_iy=initial velocity in the y/vertical direction | V_iy=Vi sin θ

y= (V_f²-V_i²)/a*2- formula for maximum displacement/height when final velocity is 0 during projectile motion.

second fromula for max height/displacement= ½ V_iy²/2g

t=V_f-V_i/a:time for projectile to reach its maximum when final velocity=0 | a=-9.8

when acceleration is constant: average velocity= (V_f+V_i)/2

When acceleration is constant: X(displacement)=(V_f+V_i)/2*time

When acceleration is constant: time= (V_f-V_i)/a

Rage formulas: V_ix*time | V_i²sin2θ/g or -9.8| 2v²cosθ*sinθ/g

Vertical displacement formula: V_iy*time-1/2*g*t² | V_iy=Vsinθ
