Rolling friction or rolling drag is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects, that is, not all the energy needed for deformation of the wheel, roadbed, etc... is recovered when the pressure is removed.

Another cause of rolling resistance lies in the slippage between the wheel and the surface, which dissipates energy.

David Grossman has become the first Israeli author to win the 2017 Man Booker International prize for his novel “A Horse Walks Into a Bar”. The novel was translated by Jessica Cohen and is published in Britain by Jonathan Cape. The book is an ambitious high-wire act of a novel that shines a spotlight on the effects of grief, without any hint of sentimentality. Since 2016, the Man Booker International Prize awards both the winning author and translator £25,000. To be considered for the prize, books had to be translated into English and published in the UK between May 1, 2016 and April 30, 2017.
