IB Physics Animations: 4 Sims for IA Data and Exam Practice
The fastest way to build real understanding of IB Physics is to combine trusted simulation collections with structured practice. PhET Interactive Simulations, The Physics Classroom and university animation libraries give you syllabus-relevant visuals for mechanics, waves and circuits. Used as mini-labs rather than passive videos, they help you gather repeatable data and turn visual intuition into exam-ready answers, especially when paired with examiner-authored practice from a platform such as Tiber Tutor.
TL;DR:
- Read PhET teacher guides before measuring, because idealized friction and circuit components affect which readings are trustworthy and must be disclosed in an investigation.
- For waves, use The Physics Classroom’s particle wave and ripple tank interactives to measure wavelength and frequency, while PhET’s Pendulum Lab shows damping and energy transfer.
- Build an investigation by changing one variable, keeping controls fixed, and recording five data points; then compare measurements with theory and note model limits.
- After exploring a free simulation, take a matching topic test while the visual is fresh; simulations build intuition, but mark scheme practice trains exam wording.

Where to find high-quality IB physics animations
A handful of collections cover almost everything the DP Physics syllabus asks of you, and knowing which one to open saves real revision time.
- PhET Interactive Simulations offers broad topic coverage across mechanics, electricity, waves and modern physics, with teacher guides that explain measurement tools, pause and step controls, and model simplifications for each sim.
- The Physics Classroom focuses on waves and oscillations, with interactives such as the particle wave simulation accompanied by notes and printable activity sheets.
- University animation collections, including Penn State’s mechanics animations index, organise demonstrations by topic, which suits quick revision checks on projectile motion or energy transfer.
Before opening any of these, it helps to check what the syllabus actually expects you to demonstrate. The IBO’s physics subject brief confirms that practical work and simulations remain a core part of the DP Physics course, which means time spent in a well-chosen sim is time spent on assessable skills, not a distraction from them.
PhET’s guides are particularly useful here because they spell out where a simulation simplifies reality, such as how electrons are represented in a circuit or how friction is modelled in a pendulum. Reading that guide before you touch the sim means you walk in knowing which measurements are trustworthy and which are illustrative only. For a map between topics and assessment objectives, our IB Physics syllabus guide sets out exactly which sub-topics each paper tends to draw on.
Best sims by IB physics topic and what to explore in each
Different sims suit different parts of the syllabus, and each rewards a slightly different approach once you open it.
- Mechanics: projectile motion, kinematics and circular motion. Vary launch angle and initial velocity, use the built-in measurement tools to record range and time of flight, and plot the resulting graphs against the kinematic equations you have learned.
- Waves and optics: particle wave, ripple tank and transverse sine wave maker. Measure wavelength and frequency directly on screen, then slow the animation to observe interference patterns forming as two sources overlap, a technique the Physics Classroom’s interactive notes describe in detail.
- Electricity and magnetism: Circuit Construction Kit (AC/DC) and RLC circuits. Build a simple series circuit, measure the time constant as a capacitor charges, and compare how current behaves under AC versus DC supply, using the PhET teacher guide to check which meter readings are idealised.
- Oscillations and resonance: pendulum lab and mass-spring sims. Record the period across several amplitudes, switch on the energy graph to watch kinetic and potential energy exchange, and introduce damping to see how amplitude decays over time.
One activity ties several of these together neatly: use a pendulum sim to determine the gravitational field strength on an unfamiliar “Planet X” setting, then check your value by timing several oscillations and applying the period formula, exactly the kind of small, self-contained investigation an IA write-up rewards.
Pro Tip: Change one variable at a time in any sim, keep everything else fixed, and you have the control you need for a credible IA-style data table.
How to use animations effectively for IB revision and practical work
Watching a simulation run is not the same as studying it, and the difference comes down to structure. A simple four-step routine turns any animation into proper revision: observe the behaviour qualitatively first, then take quantitative measurements, then record those readings with a sensible estimate of uncertainty, and finally compare your results against the theoretical prediction.
- Record readings you can repeat, not single snapshots, since a graph built from five or six data points is far more convincing in an IA than one described from memory.
- Note where the model simplifies reality, such as the lack of air resistance in many mechanics sims or idealised components in circuit sims, and mention this explicitly in any write-up.
- Design a short investigation with one independent variable, a fixed set of controls, and at least five data points before you try to draw a conclusion.
- Translate your observation into exam language, moving from “the ball slowed down” to “the resultant force opposed the direction of motion, reducing velocity according to Newton’s second law.”
That last step matters more than it looks. Examiners reward precise physics vocabulary and correct causal language, so get into the habit of narrating what you see in a sim using the same phrasing you would use in a six-mark explain question. A sim that shows you why current lags voltage in an RLC circuit is only useful once you can write that reason down in the terms a mark scheme expects.
How Tiber Tutor uses animations and examiner-authored resources to support IB physics study
Watching a simulation builds intuition, but converting that intuition into exam marks takes structured practice against real mark schemes. We built our animated videos, exam-style questions, topic tests, mock exams and flashcards with experienced educators and IB examiners, so every resource reflects how a topic is actually assessed, not just how it looks in a demo.
- Examiner-authored animations walk through the same mechanics, waves and circuit concepts you explore in PhET or the Physics Classroom, but frame them around syllabus statements and command terms.
- Integrated analytics and syllabus monitoring track which topics you have watched, practised and tested, so visual learning turns into a measurable trend rather than a one-off session.
- Student-led answer review against examiner mark schemes shows you exactly where a correct idea lost marks for imprecise wording.
A sensible workflow is to explore a concept freely in an open sim first, then move straight to the matching topic test on our platform while the visual is still fresh, which cements understanding far faster than revisiting notes alone.
Guidance on assessing student understanding using animations
Simulations are useful for teaching, but they also double as quick formative checks once you know what to look for. The clearest sign of genuine understanding is prediction: before you change a variable in a sim, write down what you expect to happen and why, then run it and compare. A student who predicts correctly and explains the mechanism has understood the physics; one who only describes what happened on screen has observed it, which is a weaker form of knowledge.
Short, low-stakes quizzes immediately after a sim session work well for the same reason. Ask yourself, or have a study partner ask you, to explain a graph the sim just produced without looking at it again. If you can reconstruct the shape of a velocity-time graph or an energy transfer diagram from memory, the concept has transferred from the screen to your own understanding.
Teachers often build this into lessons with a “predict, observe, explain” sequence, and you can run the same three steps alone during revision. Pairing this with our flashcards for quick recall, followed by a short topic test a day or two later, gives a reasonably reliable check on whether a concept has actually stuck rather than just felt familiar in the moment.
Why visual learning matters for IB physics
In my own experience helping students revise, the misconceptions that resist flashcards usually dissolve the moment a student watches energy shift between kinetic and potential in a pendulum sim. Animations earn their place by making the invisible visible, but they work best alongside past papers and examiner mark schemes, never instead of them.

FAQ
Are PhET simulations accurate enough for IB coursework?
PhET sims are built with documented model simplifications, such as idealised friction or simplified electron behaviour, which the teacher guides explain clearly. They are reliable for demonstrating relationships and gathering trend data, but you should note any simplification when writing up an IA-style investigation.
Which simulation is best for IB waves and oscillations topics?
The Physics Classroom’s particle wave and ripple tank interactives are strong choices for wavelength, frequency and interference, while PhET’s Pendulum Lab suits period, damping and energy transfer in oscillations. Both come with measurement tools suited to recording data for graphs.
How do I turn a simulation activity into exam practice?
Observe the sim, take measurements, then rewrite your observations using precise physics vocabulary and the command terms examiners use, such as “explain” or “determine.” Following this with a matching topic test checks whether that understanding holds up under timed conditions.
Does Tiber Tutor include animated videos for IB physics?
Yes, our platform includes animated instructional videos alongside exam-style questions, flashcards and mock exams, all authored by experienced educators and IB examiners. Plans start from £9 per month on the Per-Subject Plan.
What is the difference between IB SL and HL when using simulations?
The same simulations generally suit both levels, since the underlying physics does not change between SL and HL. The depth of the follow-up questions does, so HL students should extend an exploration with additional variables or more detailed calculations, which our notes break down by level.
