- Homework Statement
- I saw the following in my book and it confused me. This was under the section on drift velocity of electrons In a conductor.

##\vec {v_1}= \vec {u_1} + \vec {a} t##

In the above equation, ##\vec {v_1}## is velocity of electron just before it collides with a fixed ion, ##\vec {u_1}## is the velocity of electron just after the last collision with another ion and ##\vec {a}## is the constant acceleration of the electron in question when a uniform electric field is applied to the conductor.

- Relevant Equations
- Suvat equations of motion

To my understanding, suvat equations must apply when motion is one dimensional and also the acceleration is constant pointing in the direction of motion or against the direction of motion. So I'm not sure about this.

Perhaps, the vector form just means that we can select an axes system (i.e. x and y axes) and resolve each vector in the suvat equation along this axes system; now we would have constant acceleration along x and y axes and we could apply the suvat equation to the x axis components and separately to the y axis components.
