Next exam for M3: Wednesday 16th May
In general: v = r \omega
where \omega is the angular speed in rad \, s^{-1} , r is the radius of the circle in metres,
and v is the velocity in ms^{-1} .

You can get a better display of the maths by downloading special TeX fonts from jsMath. In the meantime, we will do the best we can with the fonts you have, but it may not be pretty and some equations may not be rendered correctly.

Glossary

angular speed

the rate at which the angle changes in circular motion

circle

a conic curve with equation (x-a)²+(y-b)²=r²

speed

velocity without direction; a scalar quantity

union

The union of two sets A and B is the set containing all the elements of A and B.

velocity

the rate of change of displacement. It is a vector quantity with magnitude and direction.
