Rafa- Lubrication: Applying lubricants such as oil or grease between surfaces can reduce friction by creating a smooth barrier between them.
- Polishing surfaces: Smoothing and polishing surfaces can help reduce friction by minimizing roughness and irregularities that cause resistance.
- Using bearings: Utilizing bearings in mechanical systems can help distribute forces evenly and reduce friction between moving parts.

What are ways to overcome friction other than using lubricants?
Some ways to overcome friction other than using lubricants include using ball bearings or roller bearings to reduce surface contact, polishing surfaces to reduce roughness, and using materials with lower coefficients of friction. Additionally, applying a coating or plating to surfaces can reduce friction by creating a smoother surface.
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false?
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
What are the ways on how to overcome the effects of friction in performing task daily activities?
To overcome the effects of friction in daily activities, you can use lubricants such as oil or grease to reduce friction between surfaces. Using proper tools and equipment designed for the task can also help minimize friction. Additionally, maintaining the equipment by cleaning and lubricating it regularly can reduce friction and improve performance.
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
What does the friction graph reveal about the relationship between surface roughness and the force required to overcome friction?
The friction graph shows that as surface roughness increases, the force required to overcome friction also increases. This indicates that there is a positive relationship between surface roughness and the force needed to overcome friction.
