Translation of "to feel" into Portuguese

I touched a cop on the way into work yesterday just to feel something.

Eu apalpei um policial ontem, só para sentir algo.

The children were made to feel that they already worked as hard as they could.

Os jovens passaram a achar que já se haviam empenhado tão arduamente quanto podiam.

I, at that point, was starting to feel as though there was something not quite right.

Naquele momento, comecei a pressentir que algo ia correr mal.
