I Centre of Gravity: How Can This Be Possible?

AI Thread Summary
The center of gravity is the point where the weight of an object appears to act, but it does not represent the actual point of force application for each particle. Gravity acts on all particles within the object equally, leading to the concept of the center of gravity being a point of balance. When a force is applied in line with the center of gravity, it generates no torque, allowing for stable equilibrium. Additionally, a moment refers to the turning effect produced by a force applied at a distance from a pivot point. Understanding these concepts is crucial for analyzing forces and motion in physics.

Hi... The centre of gravity is the point where the whole weight seems to act on. How can this be possible? Ty in advance

Actually, the center of gravity is not where the whole weight acts on. The force of gravity acts on each particle in the object at roughly the same magnitude. It's merely the point where if you apply a force that is inline with it, no torque is generated.

Thanks for answering as soon as possible. Is a moment a turning effect of a force (the rotation) or when applying the force. Ty
 
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...
