LEC3

• Studied motion with constant acceleration.
• Velocity changes by the same amount per unit time.
• Equations of motion.

Since acceleration is constant, we can make some assumptions about it.

$$\begin{array}{r}a=\text{const}\\ a=a_{avg}\\ a=\frac{v-u}{t}\\ v=u+at\end{array}$$

Position

Area under a v-t curve.

• Area of Rectangle + area of triangle

$$s=ut+\frac{1}{2}a{t}^2$$

(always a parabola cuz of $t^2$).
