Can you mimic the contact force you feel on Earth?

image with no caption

The difference between standing on the ground and freefalling is the contact force that the ground exerts on you. This is the force that the astronauts want to experience.

If you can make each astronaut experience a contact force equal to the size of his weight, as he does on Earth, he should be able to walk around the space station just like he can on Earth.

But how can you make someone experience a contact force like this?

On Earth, you experience your weight because of a contact force from the ground.

Sharpen your pencil

Imagine yourself in these scenarios. Draw the contact force you experience in each situation as a result of the acceleration, and write down what you FEEL. For instance, “Something’s pushing me in the back.”
