low shear strength
Graphite is made up of layers of carbon atoms, which can easily slide over each other. this means that graphite is slippery, making it a good lubricant. (good at reducing friction
it is slippery because it can be and because the bonds between there layers are weak
True
Lubricant (Liquids, oils, grease, fats, water, graphite...)
A lubricant such as oil, grease, graphite powder or PTFE can reduce the friction between two surfaces. Or using metal balls to space them and reduce the contact surface area as used in ball bearings.
friction is a force which opposes the direction of the movement of a certain body. reducing the friction between moving parts will lead to an increase of acceleration or speed of that particularly body.
No, sand does not reduce friction but increase friction.
Lubrication to reduce friction. To increase friction step on the brakes.

Graphite has many applications. Powdered graphite is used to reduce friction between machine parts, engine casings on aerospace vehicles, and shielding high voltage power cables.

Graphite
Lubricants such as oil, grease, and graphite are commonly used. However, simply keeping a liquid coating (even water) may help reduce friction. In many applications, surfaces can be made with very smooth substances such as polished metal, ceramics, or teflon.
oil, graphite, grease
yes because when they brake the friction is caused to reduce
