Friction has several top advantages. It allows the pen tip to deposit ink smoothly on paper, helps firmly hold the pen or pencil in hand, and prevents it from slipping. Friction also enables precise control over writing movements.
Different effects of Friction:
Effect of Contact Friction
- Prevents motion, generates heat.
- Causes wear and tear, slows down objects.
- Reduces efficiency, wears down tires.
Effect of Fluid Friction
- Slows down motion in fluids, generates heat in fluids.
- Reduces speed, increases fuel consumption.
Effect of Internal Friction
- Reduces vibrations, dissipates energy.
- Causes energy loss, leads to material fatigue.
Effect of Surface Friction
- Causes heat generation, leads to surface damage.
- Reduces wear, improves efficiency.
