TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
by reducing the mass you reduce the friction, and by reducing the friction reduce the fuel needed to move the car, this applies to all cars not only CO2 cars.
by increasing smothness wecan decrease the friction and vice versa

Lubrication will help in reducing friction in a very smooth manner. It is a process that prevents solid to solid contact which would cause friction. You would need to use a lubricant such as oil or water for lubrication.
Work equals force times distance. In reality, you don't decrease the force by the same proportion that you increase the distance because of friction. In English, you need less power (work per unit of time) to complete the task, but it takes more work (energy) because of more distance of friction.

A. By decreasin the work inut to the machine without increasing output B. By reducing losses due to friction C. By increasing the ork ouput of the machine wihout increasing input D. All of the above D. ALL OF THE ABOVE
no. No because we would need to overcome friction when moving, causing us to move slower.
Actually, they don't. Are you talking about reducing pollution?
One way to reduce friction is to use a lubricant.
