Question

Name two things that reduce friction

Answer 1

Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction. ...Lubrication is another way to make a surface smoother. ...Make the object more streamlined. ...Reduce the forces acting on the surfaces. ...Reduce the contact between the surfaces.

Answer 2

Reducing the normal force against the ground will reduce the amount of friction force, you can do this reducing the weight or mass of the object that you want to move.

Smoothing down the surface, for example, on a wet floor, the water fills some of the little imperfections in the ground, so the coefficient of dynamic friction in the ground is reduced.
