1. SUVAT Variables

"Students Universally Value Achieving Top"

• S — Displacement (s)
• U — Initial velocity (u)
• V — Final velocity (v)
• A — Acceleration (a)
• T — Time (t)

2. Which equation omits which variable?

"SVT — Sgt. V is absent, Time is absent, s is absent"

• Equation 1: v = u + at → omits S
• Equation 2: s = ut + ½$at^{2}$ → omits V
• Equation 3: $v^{2}$ = $u^{2}$ + 2as → omits T

3. Projectile Trig Pattern: THR

"Take Height — Single, Squared, Synced"

• T (time): $\sin\theta$ (power 1)
• H (height): $\sin^2\theta$ (power 2)
• R (range): $\sin 2\theta$ (double angle)
• All denominators: g, 2g, g

4. Complementary Angles

"30 and 60 — Same Range, Steeper is Higher"

• Same range because $\sin(2\times30°) = \sin(2\times60°) = \sin 60°$
• 60° → 3× the height of 30°

5. Centripetal vs Centrifugal

"Centripetal = Centre-seeking (REAL force on rotating body)" "Centrifugal = Centre-fleeing (PSEUDO force in rotating frame)"

6. Graph Rules

"SAVE — Slope And Velocity-time gives Everything"

• Slope of x-t = velocity
• Area under v-t = displacement
• V-t slope = acceleration
• Everything else is derived
