When you stand still on the ground, how large a force does the ground exert on you?

Question

Why doesn't this force make you rise up into the air?

Answer 1

Unless your body is accelerating, the net force on it must be zero. That means the ground pushes up with a force equal in magnitude, but opposite in direction, to the force of gravity on your body (aka weight).

Answer 2

The force you exert on the ground is equal to how much force the ground is exerting to you. The force that you exert on the ground is equal to your weight, therefore, the ground exerts a force that is equal to the magnitude of your weight but in an opposite direction (upwards).

Answer 3

A force equal to your weight.

Because your weight is pressing down by the same amount.

.

Answer 4

Equal to your weight in magnitude.

Reason: - You are standing still. This means your acceleration is zero. Therefore, total force on you are zero. There are two forces on you.

1. Your weight, which is in downward direction

2 Force by the ground in upward direction

For total force to be zero, the above two forces should balance each other.

Therefore,

force by the ground = your weight in magnitude.

Answer 5

Newton's third Law:

You press down on the ground with force of mg.

The ground reacts by pressing up with the same force.

If you have a mass of 50kg, mg = 50*9.81 = 490.5N

You press down with a force of 490.5N

The ground presses up with a force of 490.5N

Because the resultant force of your 490.5N down and the ground's upward force of 490.5N up is zero.

Answer 6

One g.

Answer 7

every action has an "EQUAL" and an opposite reaction!
