The role of reaction to the gravitational force on a body

AI Thread Summary
In orbital mechanics, a body orbiting the Earth experiences gravitational force, which acts as the centripetal force necessary for its circular motion. There is no normal reaction force in the traditional sense, as there is no supporting surface for the object in orbit. Instead, the gravitational force itself is responsible for maintaining the orbit, and it does not convert into a normal force. The concept of a resultant force towards the center of the Earth in this context is not applicable, as the gravitational force alone dictates the motion. Therefore, the normal reaction force does not play a role in orbital dynamics.

What happens to the normal reaction of the force of gravity on a body orbiting around the Earth? The force of gravity provides the centripetal force, but does all of it get converted to centripetal force? Is there any kind of resultant force towards the centre of the Earth (due to the normal reaction)? If so, how it is obtained and what is its role ? If not, what exactly happens to it?

The so-called "normal force" is usually a force exerted by a surface that is supporting an object. For a body in orbit there is no support surface or normal force.

Is that what you meant by "normal reaction force"?
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
