What are the effects of friction on motion and ... - JSS2 Basic technology Forces and Friction Question

  Friction affects motion by opposing the movement of objects, which can be both beneficial and detrimental. Beneficially, friction allows us to walk without slipping and enables vehicles to grip the road. It also helps in tasks like writing or holding objects. However, friction can be detrimental by causing wear and tear on mechanical parts, leading to damage and reduced lifespan. It also generates heat, which can decrease the efficiency of machines. Managing friction through lubrication and smoothing surfaces is crucial to harnessing its benefits while minimising its drawbacks.
