Question

Quizplus · Accepted Answer

Weight is a force exerted on an object due to gravity. In orbit, Mort is in free fall and experiences weightlessness. However, he still has mass, and the Earth's gravity is still pulling on him. This means that his weight is not zero, but it is a little less than 700 newtons.
