Tony Posted April 2, 2018 Author Report Share Posted April 2, 2018 Amazing the weakest force has the strongest influence. Quote Link to comment Share on other sites More sharing options...
adam_r Posted April 3, 2018 Report Share Posted April 3, 2018 Not very weak though Tony. It can and will accelerate objects at 9.81m/s/s until they reach terminal velocity. Without air resistance (in a vacuum) a hammer and a feather will fall at the same rate until the feather has reached its terminal velocity. The hammer will continue to accelerate at 9.81 meters per second per second Quote Link to comment Share on other sites More sharing options...

The hammer will continue to accelerate at 9.81 meters per second per second If they are falling in a vacuum under only the force of gravity, what would cause the feather to cease to accelerate i.e. to reach a terminal velocity?

Rich Posted April 3, 2018 Report Share Posted April 3, 2018 What happened there, they took the engine out which made the rear too heavy so it fell back? Quote Link to comment Share on other sites More sharing options...

Very true! In a vacuum both object t will fall at the same rate. Quote Link to comment Share on other sites More sharing options...
Tony Posted April 3, 2018 Author Report Share Posted April 3, 2018 What happened there, they took the engine out which made the rear too heavy so it fell back? Yep....Remember some time back i posted a pic of a Lotus falling backwards after a front wheel was removed. Quote Link to comment Share on other sites More sharing options...
