Think about your own experiences while flying. When are you forced back into your seat the most?
I call this plain wrong. If this was true there would be no need for brakes to be locked on the catering trolleys in a passenger cabin, and people would levitate from their seats. As I understand it, all objects in an aeroplane are travelling at the same speed, but because of the slight nose-up flying attitude, gravity still 'pulls' items to the rear of the aircraft. Test it yourself when you walk in an aircraft in flight. Gravity certainly does exert force on any object in an aeroplane (and I hope I don't need to rely on your expertise in this field)
