Embibe provides sample questions for NCERT Class 8 Science for. We have provided some important points to remember for NCERT Class 8 Science chapter 12 as mentioned below:

• Friction: The opposing force acting when two surfaces in contact slide or tend to slide relative to one another.
• Friction always acts in the direction opposite to the direction of the relative motion of contact surfaces.
• Friction brings about wear and tear and increases energy consumption in operating machines.
• Ball-bearing: A device used for reducing rolling friction, by making an axle to move over metal balls placed around it radially.
• Lubricant: A material which, when applied between two surfaces in contact, reduces the friction.
• Friction can be reduced by – (a) using lubricants, (b) using soap solutions, (c) using fine powders, (d) polishing surfaces, (e) streamlining, (f) converting sliding friction into rolling friction.
• Friction is caused due to interlocking of irregularities of two surfaces in contact with each other.
• Irregularities: Uneven projections on the surfaces of a body.
• Limiting friction: The maximum force of static friction acting, when the surface of one body is about to slide over the surface of another body.
• Rolling friction: Friction experienced by a body when made to move over roller/wheels.
• Static friction: The force of friction acting between the contact surfaces, when one tries to move with respect to other.
