Calculate from any of the four kinematic equations (suvat) to determine displacement, initial velocity, final velocity, acceleration or time.
Start by adding three of the known variables to calculate any of the remaining unknowns.
Equation 1 | Equation 2 |
---|---|
\begin{gather} v\ =\ u+at\\ \notag \end{gather} | \begin{gather} s\ =\ ut\ +\ \frac{1}{2} \ at^{2}\\ \notag \end{gather} |
Equation 3 | Equation 4 |
---|---|
\begin{gather} v^{2} =u^{2} +2as\\ \notag \end{gather} | \begin{gather} s=\frac{( u\ +\ v) \ t}{2}\\ \notag \end{gather} |
The equation table shows the four kinematic equations presented in the IB Databook where: s is displacement in m, u is the initial velocity in ms-1, v is the final velocity in ms-1, a is acceleration in ms-2, and t is time in s.
