What does $u$ stand for in SUVAT?

Initial velocity.

What does $v$ stand for in SUVAT?

Final velocity.

What does $a$ stand for in SUVAT?

What is the acronym for the equations of uniform motion?

SUVAT.

By considering PHOTO, what is a general equation for the area under the graph?
\[\text{area} = ut + \frac{v - u}{2}\]

What is the area under a velocity time graph?

Displacement.

What is the SUVAT equation for $v$ involving $u$, $t$ and $a$?
\[v = u + at\]
What is the SUVAT equation for $v^2$ involving $s$, $a$ and $u$?
\[v^2 = u^2 + 2as\]

What is the SUVAT equation for $s$ involving $u$, $t$ and $a$?
\[s = ut + \frac{1}{2} a t^2\]

What is the SUVAT equation for $s$ involving $v$, $t$ and $a$?
\[s = vt - \frac{1}{2} a t^2\]

In the formula for displacement $s$ involving $\frac{1}{2}at^2$, what’s the two difference between the equations for $u$ and $v$?
\[s = ut \oplus \frac{1}{2} a t^2 \\ s = vt \ominus \frac{1}{2} a t^2\]

What is the SUVAT equation for $s$ involving $u$, $v$ and $t$?
\[s = \frac{1}{2}(u + v)t\]

What’s the geometric interpretation behind $v = u + at$?
