SPM Physics:AHA! EV Battery Choice: More Energy, Less Mass

 

On the assembly line, the car looks complete — but the empty space for the battery decides its future. Engineers debate: heavy battery or light battery, series or parallel, dry cell or wet cell? Many assume the heaviest battery stores the most energy, but physics says otherwise.

The comic teaches the Battery Insight Checklist:

• Higher EMF (Voltage) → More electrical energy, greater motor output, faster acceleration.

• Lower Battery Mass → Less inertia, lighter vehicle, quicker response.

• Series Arrangement → Voltage adds up, higher total EMF.

• Dry Cell → Practical, lower maintenance.

Lesson: Engineers weren’t looking for the biggest battery, but the most suitable one. More energy, less mass, better acceleration. AHA! Moment: Physics teaches: higher EMF and lower mass give better acceleration. Life teaches: suitability, not size, determines performance.

AHA! More energy, less mass. Suitability beats size. Not by sight, but by INSIGHT!

SPM Physics:AHA! Directly Proportional: Evidence Before Words

 

SPM Physics loves precision. Many students write “Resistance is directly proportional to Temperature” — but that’s exam danger. Two quantities increasing together does not automatically mean directly proportional.

The comic teaches the Directly Proportional Test:

1. Are both physical quantities defined? ✔

2. Is the graph a straight line through the origin? ✔

3. Is there a physics law supporting it? ✔

Examples:

• YES: Force ∝ Extension (Hooke’s Law), Current ∝ Voltage (Ohm’s Law), Weight ∝ Mass.

• NO: Resistance vs Temperature, Depth vs Pressure, Frequency vs Wavelength (same wave speed).

The lesson is simple: don’t memorise shortcuts. Prove it with data, graphs, and laws. One careless “∝” symbol can cost marks. AHA! Moment: Physics teaches: “increasing together” ≠ “directly proportional.” Life teaches: evidence before words, proof before claims.

AHA! Two lines may rise. One law makes them proportional. Not by sight, but by INSIGHT!

SPM Physics:AHA! The Cold Comes First: Evaporation and Energy Transfer

 

SPM Physics is everywhere — even before an injection. The cold sensation from isopropyl alcohol is not because the liquid is cold, but because evaporation requires energy. That energy is absorbed from your skin, causing heat loss, temperature drop, and the cooling effect.

• Cause → Effect Chain:

  • Alcohol placed on skin (liquid)

  • Evaporates (liquid → gas)

  • Energy required for phase change

  • Heat absorbed from skin

  • Skin loses thermal energy

  • Temperature decreases

  • Cooling effect occurs

Formula reminder:

$$Q=m\times L$$

Beyond the exam, this comic reflects a deeper truth. Science is not only about marks — it is about noticing invisible energy transfers all around us. The world is always teaching; the question is whether we notice. AHA! Moment: Physics teaches: evaporation absorbs heat, cooling the skin.

Life teaches: invisible transfers shape our reality — if we notice them.

AHA! Cold comes first. Energy transfers unseen. Not by sight, but by INSIGHT!

SPM Physics:AHA! SPM 2026 Physics Timetable & Survival Guide

 

The official SPM 2026 examination timetable has just been released by LPM! If your Physics score left you worried, stop asking “So What?” and start asking “NOW What?”.

This special comic brings together Cikgu Lim and AHA! Crab to remind students: Physics is not just about formulas — it’s about mindset. Cause leads to effect, present action leads to future result. The timetable is not a threat, it’s a map. Every day is a chance to add one mark back, one step closer to success.

AHA! Moment: Physics teaches: present action → cause → effect → future result. Life teaches: the past is data, the future is possibility, but only NOW changes reality.

AHA! Past is data. Future is possibility. NOW is reality. Not by sight, but by INSIGHT!

SPM Physics:AHA! The Nucle Family: One Word, One Mark

 

SPM Physics loves precision. One wrong word, one lost mark. This comic introduces the “Nucle Family”:

• Nucleus → One atomic centre containing protons and neutrons.

• Nuclei → Plural form, many centres.

• Nuclear → Adjective, relating to the nucleus (nuclear energy, nuclear reactor).

• Nucleon Number → Total number of protons + neutrons.

The lesson is simple: scientific language matters. “Nuclear contains protons” is wrong. “The nucleus contains protons” is correct. One precise word protects one precious mark.

Beyond the classroom, this comic reflects our age. In today’s AI‑driven world, words are everywhere — prompts, commands, shortcuts. But precision is rare. Machines can generate endless text, but they cannot care about the weight of a single word. Physics teaches us that accuracy in terminology earns marks; life teaches us that accuracy in meaning earns trust.
