Hello Forum,
the kinematic equations for motion with constant acceleration are vector equations which can each be expanded into 3 scalar (or component equations). The vector equations are:
v_f = v_0 + a (Delta_t)
r_f = r_0 + v_0 (Delta_t) + (0.5) a (Delta_t)^2
r_f = r_0 + (0.5) (v_f + v_0) (Delta_t)
From these three vector equation we can write the corresponding scalar equations for the x,y and z components.
What about the scalar equation (v_f)^2 = (v_0)^2 +2a (x_f -x_0) ? It can be written for each scalar component.
What is the corresponding vector equation for it from which it comes from?
thanks
