Thanks that makes sense now :)

Hi Alan Here, good with electrical/electronic but found wanting in general Physics - That's why I'm here :)

Apologies for what I assume is a rookie question. Given F=ma if you have a 1 kg object traveling in e.g. space say x @ 100m/s then F = 0 on that object. If you have another 1kg object say y sitting at 0 m/s, F=0. If they impact there must be force involved? Does negative acceleration give you a...
