WebKinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. WebDisplacement is defined to be the change in position of an object. It can be defined mathematically with the following equation: \text {Displacement}=\Delta x=x_f-x_0 Displacement = Δx = xf − x0. x_f xf refers to the value of the final position. x_0 x0 refers to the value of the initial position.

WebW net = W grav = − m g ( y f − y i), where y is positive up. The work-energy theorem says that this equals the change in kinetic energy: − m g ( y f − y i) = 1 2 m ( v f 2 − v i 2).
