IB DP Physics lesson pack on graphical analysis of motion for Topic A.1 Kinematics, SL and HL, first assessment 2025: gradients, areas, tangents and chords on position-time, velocity-time and acceleration-time graphs. Editable worksheet, 43-slide lesson deck, teacher key, worked solutions and a questions-only assessment, supplied as self-contained HTML plus colour and black-and-white PDF.

What students learn

The gradient of a position-time graph is the velocity, and the gradient of a velocity-time graph is the acceleration.
Where a graph curves, the average velocity is the gradient of a chord and the instantaneous velocity is the gradient of a tangent.
Displacement is the area under a velocity-time graph, with area below the axis negative, so displacement and distance come apart. The area under an acceleration-time graph is the change in velocity.
Five explained multiple-choice questions, and a ten-mark data question in the Paper 1B pattern: a trolley timed at a light gate, a supplied graph with error bars and one reading to add, the acceleration from the gradient, the distance from the area, and a systematic error read from where the line meets the time axis.

IB skills (Tool 3: Mathematics, with Inquiry 3: Concluding and evaluating):

Interpret the features of a graph: gradient, changes in gradient, intercepts, maxima and minima, and area (taught).
Sketch velocity-time and acceleration-time graphs with labelled but unscaled axes (practised).
Draw and interpret uncertainty bars (practised).
Identify and discuss random and systematic errors (practised).

What’s included:

Student Worksheet - 18 pages
Teacher Key - 24 pages
Worked Solutions - 17 pages
Assessment - 15 pages
Lesson deck - 43 slides

It builds on the speed, velocity and acceleration packs, and leaves the suvat equations to the follow-on packs. Worksheet and deck open in any modern browser with nothing to install, and the worksheet is fully editable. SI units, IB notation and IB command terms throughout. Suitable for grades 11-12 (ages 16-19) as a lesson, cover lesson, homework or revision.

IB DP Physics (2025) A1 Kinematics Complete Unit Bundle

The complete Topic A.1 Kinematics unit for IB DP Physics, SL and HL, first assessment 2025, bundled into one sequenced teaching unit and priced 30% below the cost of buying the packs separately. **What's in the unit** - Nine lesson packs in teaching order: Distance and Displacement, Speed and Velocity, Acceleration and Non-Uniform Motion, Graphical Analysis of Motion, SUVAT Equations I and II, Projectile Motion I and II, and Fluid Resistance. - A1.P1, a full double-period bench practical measuring the acceleration of free fall, aim to evaluation, with honest sample data. - SL and HL topic tests with AO-tagged mark schemes, for end-of-topic assessment. - Skill packs for targeted drill on scientific notation, significant figures and unit conversion. Together the lessons cover all nine understandings of Topic A.1: position, displacement, velocity and acceleration, motion graphs, the four suvat equations, projectile motion, and the qualitative effect of fluid resistance. **Every lesson pack includes:** - An editable student worksheet - A teacher key with every answer and marking point - Worked solutions with every step and its units - A questions-only assessment with IB mark allocations - A choreographed lesson deck with staged reveals **IB skills (mostly Tool 3: Mathematics)**: identifying scalars and vectors, determining rates of change, drawing and adding vectors, converting units, selecting and rearranging the suvat equations, resolving vectors into perpendicular components, interpreting and sketching motion graphs, and linearizing data. The practical adds Tool 1 experimental technique and the Inquiry skills: measuring time and length, recording and propagating uncertainties, plotting best-fit lines, and evaluating error sources. Everything ships as self-contained HTML, so worksheet and deck open in any browser with nothing to install and the worksheet is fully editable, plus colour and black-and-white PDF of every projection and the slides. SI units, IB notation and IB command terms throughout. A1.1 is free, so you can teach a whole lesson before buying. Suitable for grades 11-12 (ages 16-19) for first teaching, assessment and revision. **Also in the catalogue, sold separately:** - [Resolving Vectors, the skill pack behind the projectile lessons](https://www.tes.com/teaching-resource/-13537892) - [Uncertainties, the arithmetic the practical leans on](https://www.tes.com/teaching-resource/-13538960) - [Uncertainties on a Graph, error bars and extreme gradient lines]( https://www.tes.com/teaching-resource/-13542412) *A rating helps other teachers find this.*
