When you weigh yourself, how does the support force of the scale acting on you compare to the gravitational force between you and earth?

Answer with explanation:

We know that when we weigh ourselves on a scale the scale measures the Reaction force that acts between the scale and the person who wishes to determine his weight.

The free body diagram of the person on a weighing scale is represented in the attached figure.

As we can see for equilibrium

where,

R is the reaction force between the support and the person

W is the weight of the person which by definition is the force that the earth exerts on the person.

Thus according to the above relation we conclude that that support force of the scale is equal to the gravitational force in magnitude but is opposite in direction.

it is easily magnetized.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
