Physics - Apparent weight

Apparent weight

The left hand person is standing on the ground. The normal force (N) =
the person's weight (W), the apparent weight equals the actual weight. The
right hand person is in freefall (without considering air resistance).
There is no normal force so the person is accelerating freely due to
gravity. The person's apparent weight is zero. They feel weightless.

The term apparent weight is used to describe the weight that you perceive.
Your apparent weight is equal to the magnitude of the normal force. When
you are standing on the ground the normal force is exactly equal in
magnitude to your actual weight.

When you stand on the ground you are aware of the pull of gravity because
you can feel pressure on the soles of your feet. What you are feeling is
not the gravitational force [1] but is the force [2] exerted by the ground
to resist the pull of gravity. This force is known as the normal force.

The term apparent weight [3] is used to describe the weight that you
perceive. Your apparent weight is equal to the magnitude of the normal
force. [4] When you are standing on the ground the normal force is exactly
equal in magnitude to your actual weight. [5]

You can feel weightless even when there is a gravitational force [6]
acting on you. You _feel_ weightless when there is no normal force
resisting the gravitational force. Often people describe this as being in
freefall. In freefall your acceleration equals the acceleration due to
gravity. There is no normal force to slow down your acceleration. Without
the presence of a normal force you can't feel the effect of gravity, until
you hit something that provides a normal force.
