IB Physics Formula Sheet (Data Booklet): Ultimate 2025 Guide + Must-Know Tips

The IB Physics Formula Sheet (Data Booklet) is a vital resource provided during your IB Physics SL and HL exams. Mastering its contents—and knowing its limitations—can significantly impact your exam performance. In this guide, we’ll explore what’s inside, what’s missing, and how to make the most of it.

Introduction to the IB Physics Formula Sheet (Data Booklet)

The IB Physics Formula Sheet, officially known as the Data Booklet, is a reference document containing essential equations, constants, and unit conversions aligned with the IB Physics syllabus. Both SL and HL students receive this booklet in all exam papers.
It serves as your quick-access resource during assessments, designed to minimize memorization of standard formulas and allow focus on applying concepts.

What’s Inside the IB Physics Formula Sheet?

The booklet features:

• Mathematical equations covering core physics topics.
• Physical constants (e.g., gravitational constant, Planck’s constant).
• Unit conversions for common measurements.
• Symbols and definitions to aid clarity during calculations.

Its structure:

• General formulas and constants section at the beginning.
• Topic-specific equations grouped according to the new IB Physics themes (2025 syllabus).

➡ Note: Vector notation is not generally included; formulas refer to magnitudes only.

Formulas Provided in the Data Booklet

The formula sheet includes most standard equations you’ll use in IB Physics, such as:

• Kinematic equations (without vector notation)
• Gravitational potential energy: Ep=mghE_p = mghEp​=mgh
• Work done: W=Fdcos⁡θW = Fd \cos \thetaW=Fdcosθ
• Wave speed: v=fλv = f \lambdav=fλ
• Snell’s Law: n1sin⁡θ1=n2sin⁡θ2n_1 \sin \theta_1 = n_2 \sin \theta_2n1​sinθ1​=n2​sinθ2​
• Power: P=IVP = IVP=IV

These are organized by theme (Space, Time & Motion; Fields; Waves, etc.), making it easier to find relevant equations.

Important Formulas NOT in the IB Physics Formula Sheet

Certain crucial formulas are not included, and you’ll need to memorize these for your exam:

• Average velocity: vavg=ΔsΔtv_{\text{avg}} = \frac{\Delta s}{\Delta t}vavg​=ΔtΔs​
• Newton’s second law in standard form: F=maF = maF=ma
• Conservation of momentum: m1v1+m2v2=m1v1′+m2v2′m_1 v_1 + m_2 v_2 = m_1 v_1' + m_2 v_2'm1​v1​+m2​v2​=m1​v1′​+m2​v2′​
• Impulse: J=FΔtJ = F \Delta tJ=FΔt
• Centripetal force: Fc=mv2rF_c = \frac{mv^2}{r}Fc​=rmv2​
• Rotational dynamics: τ=Iα\tau = I \alphaτ=Iα, L=IωL = I \omegaL=Iω

These omissions encourage students to focus on conceptual understanding rather than rote learning.

How to Use the IB Physics Formula Sheet Effectively

✅ Familiarize yourself with the booklet layout early in your studies.
✅ Practice solving past papers while referring to the formula sheet, so using it becomes second nature.
✅ Understand the meaning of each formula—don’t rely on plug-and-chug methods alone.
✅ Avoid common mistakes like misapplying formulas due to misunderstanding symbols or units.
✅ Use annotated versions (e.g., from RevisionDojo) to gain deeper insight into each formula’s application.

IB Physics SL vs HL: Data Booklet Usage

• Both SL and HL students use the same formula sheet.
• HL students should pay extra attention to formulas specific to HL themes, such as nuclear physics and rotational dynamics.

Where to Access the IB Physics Formula Sheet (Data Booklet)

You can:

• Download the official data booklet from your IB coordinator or IBIS platform.
• Use annotated versions from trusted IB platforms, like RevisionDojo, to help interpret and apply formulas effectively.

Tips for Mastering the Formula Sheet for IB Physics Exams

• Create a revision plan that incorporates formula booklet drills.
• Use RevisionDojo’s interactive formula tools to practice with real IB-style questions alongside the booklet.
• Regularly test yourself on formulas not included in the booklet to ensure you’ve memorized them.

Frequently Asked Questions (FAQs)

Is the formula sheet provided in IB Physics exams?
Yes, every IB Physics exam paper includes the official data booklet.

Do I need to memorize all formulas?
No, but you must memorize key formulas that are not in the booklet (e.g., Newton’s second law, impulse).

Can I annotate my own booklet?
No. Only the official IB-provided data booklet is allowed during exams.

Where can I download the latest IB Physics formula sheet?
From your school’s IB coordinator, IBIS, or trusted platforms like RevisionDojo.

Are there separate formula sheets for SL and HL?
No. Both levels use the same booklet.

What is the best way to practice using the data booklet?
Solve past papers under timed conditions and use RevisionDojo’s annotated booklet resources.

Conclusion

The IB Physics Formula Sheet (Data Booklet) is a powerful tool when used effectively. By familiarizing yourself with its layout, practicing with it regularly, and memorizing key excluded formulas, you can maximize your exam performance.
Don’t just rely on the formulas—understand them, apply them, and use resources like RevisionDojo to master this essential IB Physics companion.
