ch 2 kinematics

displacement

of an object is its distance from a fixed point in a specific direction

velocity

of a body is defined as the rate of change of its displacement

acceleration

of a body is defined as the rate of change of its velocity

equations of motions

at highest point of projectile motion,

Vy = 0

horizontal component, Vx is

the same

at same height,

Vy = Uy

horizontal projectile motion equations

Vertical projectile motion equations
