SUVAT Super Selector!

Tired of mixing up your motion equations like $v=u+at$ and $s=ut+\frac{1}{2}at^2$? There's a trick to pick the right one instantly!

Subject: mechanics • Classes: 6–12 • Difficulty: intermediate

The Trick

The secret is to focus on the *missing* variable! Each of the four core SUVAT equations (where S=displacement, U=initial velocity, V=final velocity, A=acceleration, T=time) omits exactly one of these five. To choose the right equation, simply identify the variable you *don't know* and *don't need to find*. \n1. **Missing S:** $v = u + at$ \n2. **Missing V:** $s = ut + \frac{1}{2}at^2$ \n3. **Missing T:** $v^2 = u^2 + 2as$ \n4. **Missing A:** $s = \frac{(u+v)}{2}t$ \nWhy it works: This method streamlines problem-solving by guiding you to the most efficient formula for the given information, avoiding extra steps.
