Revision sheets for IGCSE or GCSE physics. This series revision sheets
are based on the IGCSE & GCSE syllabuses. Lots of formulas, definitions and key points
to learn off. There are also accompanying test sheets to check your memorisation.
The idea is read the information and than print the quiz sheet and try the questions.
Robert Hooke
Revision Exercise two:
Forces and Motion
At terminal velocity the gravitational force down equals the air resistance force up.
vehicle stopping distance depends on the speed squared.
moment = force × perpendicular distance from pivot
weight of a body acts through its centre of gravity
principle of moments: in equalibrium clockwise moments equal anticlockwise
Hooke’s law: the force is proportional to the extension
True for the initial linear region of a force - extension graph
pressure = force / Area unit: (P) Pascal
pressure at a point in a gas or liquid acts equally in all directions
