Newton's Laws (Leaving Cert Applied Maths): Flashcards

$F = ma$

$F = \mu R$

Coefficient of friction

Normal reaction force

$W = Fs$

$P = Fv$

$P = \frac{W}{t}$

Newtons (N)

Watts (W)

Remains constant throughout

$mg \sin \theta$

$mg \cos \theta$

Net force equals zero (forces balance)

Draw force diagrams for each object

Other moves same distance $d$ in opposite direction
