Hey mate here is your answer.....

Friction can be reduced by changing from sliding to rolling.

Hope it helps ★★★★★

Answer 2

The correct response to the given question is option A: sliding to rolling.

• Friction is the resistive force that acts in the opposite direction of motion. It is caused when the roughness of two surfaces comes in contact with each other.
• The more the contact area of one surface with another surface the more the friction between them.
• Sliding friction comes into play when an object slides on the surface and rolling friction comes into play when an object rolls on surface.
• During the sliding motion of one object over another, the contact surface area is more than the rolling motion where the contact surface area is less comparatively.
• As the rolling motion has a lesser contact area, friction can be reduced.
• Hence, friction can be reduced by changing from sliding to rolling and incorporating rolling elements into an object.
