Question

equations of motion in vector notation.

Answer 1

Answer:

Since the equality of two vectors implies equality of their components, those two equations are equivalent to v x = ˙ x , a x = ˙ v x = ¨ x and similar equations for the y and z components. Therefore, a motion in three dimensions is always the superposition of three one-dimensional motions along the x , y and z axis.
