Como se calcula a velocidade média no MRU?

X = Xo + VT


Vm = deltaX/deltaT

Quais as fórmulas do MRUV?

Am = deltaV/deltaS;


V = Vo+at;


X = Xo + Vodeltat + amdeltat^/2;


V^ = Vo^ + 2adeltaX

Decomposição da força peso

Px = psenoteta;


Py = psenoteta

Força de atrito

Fate = ueN;


Fatc = ucN;

Lei de Hooke

F = Kx;

MCU - Velocidade angular

W = deltafi/deltat;


W = 2pi/T;

MCU - Módulo da velocidade

V = Wr;


V = 2pir/T;


V = 2pirf;


V = Wf;
