Frictional force is the force that opposes motion between two surfaces.
mechanical friction is when two mechanics create friction
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
Frictions
Unhelpful frictions are obstacles or barriers that impede progress, efficiency, or communication within a system or process. These can include excessive bureaucracy, conflicting instructions, lack of clarity, or outdated technology. Identifying and removing unhelpful frictions can lead to smoother operations and improved outcomes.

Friction belongs in between two contacting surfaces
To solve for the friction coefficient (μ), you can use the formula μ = F/N, where F is the force of friction and N is the normal force. First, measure the force required to overcome friction (F) and the weight of the object (which equals the normal force, N, if on a flat surface). By rearranging the formula, you can calculate μ by dividing the friction force by the normal force. Ensure that both forces are measured under the same conditions for accurate results.

Fluid friction occurs when a solid object moves through a fluid.
