There are two ways to experience weightlessness. In other words, accelerate to the Earth speeding up 22 mph every second in the air. In order for a person to feel weight, a person must sense the reaction force of the ground pushing in the opposite direction of gravity. In the absence of the reaction force a person will sink through the ground. Many amusement park rides generate the weightless sensation by accelerating down at close to 22 mph every second.
Weight is the force with which an object is pulled toward the earth by gravity.
Weight is the pull of gravity. Typical weight units are pounds and newtons. Work is the force used to move something in the direction of the force. If you hold a box, no work is being done on the box. If you drag the box, work is being done.
