WebRolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are … WebSep 21, 2024 · Drag seeding a lawn enhances the germination rate. When you drag the seed, you're covering it up with soil and pushing it into holes in the ground.
