Motion sickness can occur at any age but is most troublesome in children. Humankind was not designed to travel at speeds greater than a run and so the advent of the use of animals and machinery to take us at far greater speeds is not ingrained in our nervous system. The movement of objects passing us, in combination with irregular movements within the vestibular canal or balance centre in the inner ear, creates an unusual and unexpected neurological impulse state within the brain. The response is to attempt to stop us and a very good way to do this is to make us feel sick. As we age and become more used to travelling our brain accepts that this is not a dangerous situation and therefore the need for nausea diminishes.
Persevere with the travel because the body and brain will adjust eventually.
