7 of the Physics glossary’s terms, each with the part of the syllabus where you first meet it.
A quantity that has both magnitude and direction, such as displacement, velocity, acceleration or force.
The rate of change of displacement; a vector quantity measured in .
An arrangement of crossed electric and magnetic fields that lets through undeflected only particles with speed
A graph of velocity against time; its gradient is the acceleration and the area between the line and the time axis is the displacement.
A measure of how strongly a fluid resists flowing, symbol , measured in Pa s.
The resistive force on a small sphere moving slowly through a fluid in laminar flow, given by Stokes' law ; a special case of fluid resistance.
A meter that measures potential difference, connected in parallel across the component; an ideal voltmeter has infinite resistance.
