Horizontal Circular Motion (AQA A-Level Further Maths): Flashcards

$v = romega$

a = romega^2 = rac{v^2}{r}

F = mromega^2 = mrac{v^2}{r}

None, gravity acts perpendicular to horizontal plane

Horizontal, towards the centre of the circle

Along the tangent to the circular path

$F \leq \mu R$

Friction force between tyres and road

$R = mg$

$T = \frac{\lambda x}{l}$ ($\lambda$ = modulus, $x$ = extension)
