SPM Physics:AHA! Nuclear Challenge: Mass Defect Reveals Energy!

 

Alpha decay isn’t just about particles flying out — it’s about energy and mass defect. This comic shows the scoring path:

• Parent nucleus: Uranium‑238.

• Daughter nucleus: Thorium‑234.

• Alpha particle: Helium nucleus.

• Energy released:
  $6.848\times {10}^{-13}\text{J}$
  .

The exam clue: when energy is given, don’t ignore it. First calculate the mass defect using

$\mathrm{\Delta }m=\frac{E}{c^2}$

. Then add it to the product mass to find the original parent mass.

AHA! Mass defect unlocks energy. Not by sight, but by INSIGHT!

SPM Physics:AHA! Bungee Challenge: Long Cord, Close Limbs!

 

Before the cord stretches, two simple clues decide the jumper’s velocity:

1. Long Cord: More time to accelerate → more gravitational potential energy converted into kinetic energy → higher velocity.

2. Close Limbs: Less air resistance → less drag force → higher velocity.

The examiner only wants these two clues. Don’t over‑explain, don’t add extra steps. Just long cord + close limbs = higher velocity.

AHA! Long cord, close limbs — speed unlocked. Not by sight, but by INSIGHT!

SPM Physics:AHA! Racket Challenge: Strong, Light, Fast, Control!

 

A good competition racket isn’t about price — it’s about physics features. This comic shows the four scoring keywords:

1. Carbon Graphite (C): Strong and durable.

2. Low Mass (L): Lower inertia, easier swing.

3. High String Tension (H): Faster shuttlecock speed.

4. Cloth Grip (C): Better grip and control.

Memory code: C–L–H–C = Strong + Light + Fast + Control.

The exam clue is clear: don’t memorize numbers, memorize features.

AHA! Strong, light, fast, control — the winning racket. Not by sight, but by INSIGHT!

SPM Physics:AHA! Lantern Challenge: Upthrust Beats Weight!

 

Why does a sky lantern rise? It’s not just “hot air.” This comic shows the exam‑ready scoring chain:

1. Air inside lantern has high temperature.

2. Density of air decreases → low density air.

3. Upthrust (buoyant force) is produced.

4. Upthrust becomes greater than weight.

5. A resultant force acts upward.

6. Lantern rises into the sky.

The exam trap: don’t stop at “hot air makes it rise.” You must explain the density change and the force comparison.

AHA! Not just hot air — it’s upthrust victory. Not by sight, but by INSIGHT!

SPM Physics;AHA! Bernoulli Challenge: Spray by Pressure Difference!

 

Why does insecticide spray out when you push the piston? It’s Bernoulli’s principle in action. This comic shows the exam‑ready chain:

1. Air moves rapidly at the nozzle.

2. Fast air → low pressure at the nozzle tip.

3. Pressure inside the bottle is higher → liquid rises up the tube → fine spray produced.

The exam trap: don’t just write “liquid comes out.” You must explain the pressure difference step by step. Remember: fast air = low pressure, higher pressure pushes liquid up.

AHA! Spray comes from pressure push. Not by sight, but by INSIGHT!
