Thanks Mr. Kuruman,
I still have a doubt. Imagine that we fall from two different heights, when we fall to the ground we feel a greater force under our feet when the height is greater, but the force that we exert on the ground must be the same "mg" for both heights, therefore the normal force...
Thank you Mr. T.
I have some doubts about your answer: I understand that the vertical net force when we are standing on the ground is zero, therefore our acceleration is also zero. Ok, in free fall our acceleration is "g". Imagine that we fall from two different heights, when we fall to the...
Hi,
If we are standing on the ground, the Earth applies a force equal to our weight to us, but why do we feel a greater force when we fall to the ground from a certain height? Our weight is the same along this small height because our mass and acceleration are the same and, even so, the normal...
Good day,
If I consider my system to be an object and the earth, and the object is on the surface of the earth, then the system will have gravitational potential energy. Why couldn't I say that only the object (considering it as my system) has gravitational potential energy?
Thanks
