Question

mention any one of the way to reduce friction​

Answer 1

• Friction is the resistive force which resist relative motion.

• Friction is always produced in the opposite direction of the applied force.

• If frictional force is removed the relative motion will get smoother between the bodies.

• Frictional force can be removed by lubricating the surface. Lubrication will make the surface smoother and will reduce the friction.

• Another way could be to reduce the contact between the two bodies.

Answer 2

Following are the ways to reduce friction:

• As we know that the Providing ball bearings or wheels between the moving parts of machine or vehicles reduce friction and allow smooth movement as rolling friction is less than sliding friction.
• And we know Oiling or lubricating with graphite or grease the moving parts of a machine reduces friction.
• As we know that the Friction is the resistive force that resists relative motion.
• So, the Friction is always produced in the opposite direction of the applied force.
• We know If frictional force is removed the relative motion will get smoother between the bodies.
• As we also know that the Frictional force can be removed by lubricating the surface. Lubrication will make the surface smoother and will reduce friction.
• and Another way could be to reduce the contact between the two bodies.
