Things to remember for AS Mechanics
The SUVAT Equations
- $V=U+AT$
- $S=\left(\frac{U+V}{2}\right)T$
- $V^2=U^2+2AS$
- $S=UT+\frac{1}{2}AT^2$
- $S=VT-\frac{1}{2}AT^2$
Variable Acceleration
- ${\bf v}=\frac{d{\bf r}}{dt}$
- ${\bf a}=\frac{d{\bf v}}{dt}=\frac{d^2{\bf r}}{dt^2}$
- ${\bf v}=\int{\bf a}dt$
- ${\bf r}=\int{\bf v}dt=\int\left(\int{\bf a}dt\right)dt$
Other
- Gravity: $g=9.8m/s^2$
- Resultant Force: $F=ma$
- Friction: $F\leq \mu R$, at maximum when object is moving or about to move.
