Question

What similarities exist between rotational equations and translational equations?

Answer 1

tansilational equations                                                      rotational equations

v avg = delx/del t = x/t                                                 w avg = theta/t

v = delx/del t                                                             w = del theta/ del t

a = dv/dt                                                                alpha = dw/dt

v = v0+at                                                             w = w0 + alpha t

x = vot + (1/2) at^2                                            theta = wo t+ (1/2) alpha t^2

v^2 = v0^2 + 2as                                                   w^2 = wo^2 + 2 alpha( theta)

KE = 1/2 mv^2                                                   KE = 1/2   I w^2

F = ma                                                          T = I alpha

P= mv                                                         L = I w

F = dP/dt                                                 T = dL/dt

Pf = Pi                                                  Lf = Li
