ENGLAND
KS3 NC Science – Physics
Energy changes and transfers.
Simple machines give bigger force but at the expense of smaller movement (and vice versa): product of force and displacement unchanged.
Forces.
Moment as the turning effect of a force.
Forces: associated with deforming objects; stretching and squashing – springs; with rubbing and friction between surfaces, with pushing things out of the way; resistance to motion of air and water.
Measurements of stretch or compression as force is changed.
Force-extension linear relation.
Work done and energy changes on deformation.

KS3 NC D&T– Physics
Understand how more advanced mechanical systems used in their products enable changes in movement and force.

GCSE D&T

AQA D&T Systems and control
Motion: understand methods of changing the direction or distance of an output;
Mechanical systems: Candidates should understand how mechanical advantage can be gained using levers and gears.
Friction: Candidates should understand the application of friction and explain methods used to reduce friction.

OCR D&T Product design
Systems and structures: Natural and mechanical structures, simple mechanical and electrical systems.
Scientific principles: The importance of scientific principles in common products such as levers, and mechanisms on bicycles ; understanding how modern scientific principles and new materials have influenced the design of products.

WALES
KS3 Science
Understand the forces in devices and their relationship to work done and power.

KS3 Design & Technology
Learn about the properties and characteristics of mechanical components and apply this knowledge and understanding when designing and making products.

GCSE Physics
WJEC
Demonstrate and apply knowledge and understanding of the concept of pressure qualitatively and select and use the relationship: force = pressure / area.

GCSE D&T, Systems and Control
WJEC
Understand that mechanical systems transmit motion and convert types of motion.

SCOTLAND
Third level Science
Collaborate in investigations into the effects of gravity on objects and predict what might happen to their weight in different situations on Earth and in space.

Fourth level Science
Gain knowledge of how formulae may be used in the context of energy transfer and mechanical systems and apply them to solve problems, for example in engineering.

National 5 Physics
Use of an appropriate relationship to solve problems involving pressure, force and area.

NORTHERN IRELAND
KS3 Science & Technology
Incorporate control systems, such as mechanical, electronic or computer-based, in products and understand how these can be employed to achieve desired effects.
