Lesson details
Key learning points
- Friction is the force of one surface gripping or rubbing on another.
- Friction prevents or slows down movement between surfaces.
- Friction is caused by the roughness of surfaces.
- Lubricants are substances added between two surfaces to reduce friction.
Keywords
Friction - Friction is the force of one surface rubbing or gripping on another.
Rough - Rough surfaces are uneven or irregular, they are not smooth.
Irregularities - An irregularity is something different to what is expected.
Microscopic - If something is microscopic, it is so small you need a microscope to be able to see it.
Lubricant - A lubricant is a substance added between two surfaces to reduce friction.
Common misconception
Friction is not a force.
Provide examples of friction slowing objects and preventing them from moving when they are pushed.
