G9 Dynamics: Newton’s laws, deformation and forces:

– Hooke’s law; elastic and plastic deformation; spring stiffness; elastic limit;

– Newton’s laws; resultant force and use of F = ma;

– Newton’s law of gravitation; orbits, spacecraft motion;

– circular motion, centripetal force, angular velocity.


This unit builds on the mechanics units taught in earlier years, particularly grade 9. The materials topic has great relevance to engineering and research into the choice of materials for particular applications (e.g. cables on a cable-stayed bridge would be an interesting extension at this point). Study of gravitation is more mathematical than before but can also lead to interesting research projects linked to national and global space programmes. Studying the properties of materials provides opportunities for careful practical work and for more detailed investigations into material properties.

Compulsory laboratory works:

Determination  of Young modulus

Subject learning objective Language learning objective Subject-specific vocabulary & terminology Useful set(s) of phrases for dialogue/writing
Learners can:


define and use the terms stress, strain and the Young modulus

Learners can:


define and use the terms stress, strain and the Young modulus




stress, strain, Young modulus, spring stiffness

extrinsic property, intrinsic property

extension, force, length, cross-sectional area, load


Stress means…whereas strain means…

Spring stiffness depends on… whereas the Young modulus characterises the dependence on…

If force and cross-sectional area are doubled, then the material is under the stress.

If the length of a wire is doubled, then the strain is… under the same load.

To create other language objectives, and for additional guidance on language teaching objectives that apply to the teaching and learning of academic language, see ‘Introduction to language objectives’ above.


This unit divides into two distinct parts – materials and gravitation. These do not need to be taught sequentially. The first part revisits Hooke’s law and the behaviour of simple springs. This is used as an introduction to the mechanical properties of materials, where stress, strain and the young modulus will be defined and measured. There are opportunities for individual practical investigations into material properties and for research into applications. The second part returns to the nature of the gravitational field, developing ideas about force, energy, potential and their use to describe and explain the nature of orbits. Once again there is plenty of opportunity for research, particularly into satellite dynamics, and this might well draw on information from national resources such as the Cosmodrome. The materials topic provides plenty of good opportunities for practical work, refining methods of measurement and making careful calculations. The gravitational field topic provides opportunities for more advanced mathematical work.
