SPM Physics: AHA! Balloon Car – Newton’s Third Law in Motion

 

Why does a balloon car move forward when air is released?

• Air is released backward at high velocity.

• This produces backward momentum.

• By Newton’s Third Law, an equal and opposite reaction force pushes the car forward.

• On a smooth surface (low friction), the car moves easily.

Exam tip: Don’t jump straight to “Newton’s Third Law.” Write the full chain:

1️⃣ Air released at high velocity

2️⃣ Backward momentum produced

3️⃣ Equal and opposite reaction force

4️⃣ Car moves forward

That’s how you secure all 4 marks.

AHA! Air goes back, car goes front. Not by sight, but by INSIGHT!

SPM Physics: AHA! Pressure Everywhere – Pascal’s Principle in Action

 

Why does toothpaste flow out when you squeeze the tube?

• A force is applied on the tube.

• The force produces pressure inside the toothpaste.

• According to Pascal’s Principle, the pressure is transmitted uniformly in all directions.

• The toothpaste is pushed out through the nozzle.

Exam tip: For 2 marks, don’t stop halfway. Write both steps: pressure produced AND pressure transmitted in all directions. That’s the scoring clue.

This comic shows students that physics is practical — one squeeze, pressure everywhere!

AHA! Squeeze here, pressure everywhere. Not by sight, but by INSIGHT!

Tribute to Tun Dr. Siti Hasmah: Reflections on Life, Love, and Science

 

TGIF. As the week closes, Malaysia mourns the passing of Tun Dr. Siti Hasmah at the age of 100. A beloved wife, mother, doctor, and partner to Tun Dr. Mahathir for seven decades, her life was a rare testament to devotion and service.

Though I never met her, I once captured a remarkable portrait made from thousands of M&M’s pixels, depicting Tun Dr. Mahathir and Tun Dr. Siti Hasmah together. Looking at it now, sorrow deepens, knowing the profound grief of a husband parting from his lifelong companion.

Her legacy is more than history—it is written in grace, duty, and love. In this fast-paced modern era, such steadfast companionship is beyond words.

Let us honor her memory by cherishing every moment, loving deeply, and holding onto the beauty of our journey.

SPM Physics: AHA! Shock Absorber Saves the Stroller

 

Why do baby strollers have springs?

• When the wheel hits a bump, the spring compresses.

• The spring absorbs energy from the shock.

• Result: smoother ride, baby safe, easy 2 marks in exam.

Exam tip: Don’t just write “spring helps.” The scoring clue is:

1️⃣ Spring compresses when experiencing shock.

2️⃣ Spring absorbs energy.

This comic shows students that physics is practical — even in everyday baby strollers.

AHA! Shock → Spring compresses → Energy absorbed. Not by sight, but by INSIGHT!

SPM Physics: AHA! Liquids & Gases That Score Marks

 

Students often write only the substance name, but examiners want the property + application.

Quick memory guide:

• Water → High specific heat capacity → Effective coolant

• Ethanol → Low specific heat capacity → Heats up faster

• Mercury → Low specific heat capacity + high boiling point → Thermometers

• Hydrogen → Lightest gas → Balloons / combustion demo

• Oxygen → Supports combustion → Respiration & experiments

• Helium → Non-flammable → Safe balloon gas

• Butane → Liquefies under pressure → Portable gas cylinders

• Propane → LPG cylinders

• Neon → Emits light when excited → Neon signs

• Argon → Prevents oxidation → Light bulbs

Exam tip: Don’t just say “use water because it is cheap.” Write: water has high specific heat capacity, absorbs large heat with small temperature rise → effective coolant.

AHA! Substance → Property → Application. Not by sight, but by INSIGHT!
