Worked Solution & Example Answer:Explain the term friction - Junior Cycle Science - Question c - 2011
Step 1
Explain the term friction.
Answer
Friction is defined as the resistance to the movement of one surface over another. It is a force that opposes motion between two objects that are in contact. This resistance can occur due to the microscopic roughness of the surfaces in contact, which creates interlocking points that hinder relative motion.
Step 2
How can friction be reduced?
Answer
Friction can be reduced by various methods, including:
- Using Smooth Surfaces: Polishing surfaces to make them smoother can significantly reduce friction.
- Lubrication: Applying a lubricant, such as oil or grease, creates a film that separates the surfaces, minimizing contact and thus reducing friction.
- Choosing Appropriate Materials: Selecting materials that have lower coefficients of friction will also help in reducing friction.
