IB DP Physics lesson pack on free fall and vertical motion under gravity for Topic A.1 Kinematics, SL and HL, first assessment 2025: the equations of motion applied to bodies dropped, thrown down and thrown up. Editable worksheet, 30-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

  • Close to the Earth’s surface, with air resistance neglected, every body falls with the same constant downward acceleration g = 9.8 m s⁻², whatever its mass or shape. A stroboscopic diagram of a heavy and a light ball released together makes the case.
  • Choose a positive direction and keep it: a = -g with up positive, a = +g with down positive. At the top of a throw the velocity is zero but the acceleration is still 9.8 m s⁻² downward.
  • A marked-homework data question turns s = 1/2 g t^2 into a straight line by plotting the square root of s against t: on blank graph paper students choose scales, plot, draw a best-fit line and read g from its gradient.
  • Five explained multiple-choice questions, and exam practice with a ball thrown down from a 25 m building and a two-phase water entry where the acceleration reverses.

IB skills (Tool 3: Mathematics):

  • Appreciate when an effect can be neglected (taught).
  • Select and manipulate equations (practised).
  • Linearize a graph, plot with suitable scales and axes, draw a line of best fit and read its gradient (practised).

What’s included:

  • Student Worksheet - 13 pages
  • Teacher Key
  • Worked Solutions
  • Assessment
  • Lesson deck - 30 slides

A Nature of Science note frames free fall as a model, from the coin and feather in an evacuated tube to the hammer and feather on the Moon. The four equations are recalled in a reminder box, so the pack is self-contained. 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) A.1 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](/teaching-resource/-13537892) - [Uncertainties, the arithmetic the practical leans on](/teaching-resource/-13538960) - [Uncertainties on a Graph, error bars and extreme gradient lines]( /teaching-resource/-13542412)
