Key Stage 3
Meaning
Lubrication is when a substance is added to a surface to reduce friction.
About Lubrication
- When a lubricant is added to a surface the surface becomes more 'slippery'. This means the friction between that surface and another has decreased.
Key Stage 4
Meaning
Lubrication is when a substance is added to a surface to reduce friction.
About Lubrication
- When a lubricant is added to the boundary between two surfaces the friction is decreased.
- Lubricating Oil is a fraction of Crude Oil often used as lubrication.
- When two surfaces rub together the friction causes energy to be transferred to the thermal energy store of the objects. Lubrication of the surfaces reduces the unwanted energy transfer reducing the heating effect caused when two surfaces rub together.
- Drills often use water or oil to lubricate the surface which helps prevent the drill from getting too hot and melting.
