1 Section 13.3 & 13.4 Centripetal and Centrifugal Forces Physics Chapter 13Section 13.3 & 13.4Centripetal and Centrifugal Forces
2 Centripetal ForceCentripetal Force is a force that allows an object to follow a circular path.It is the name given to the force at right angles to the parth the objects are moving.Centripetal ForceCenter
3 13.4 Centripetal and Centrifugal Forces Gravity and electricity act as centripetal force across empty space.Washing Machines during the spin cycle, has the tube rotating at high speeds. The inner wall exerts a centripetal force on the wet clothes, forced into a circular path. The holes in the washing machine allows for the water to flow out through the holes (b/c of Newton’s First Law).13.4 Centripetal and Centrifugal ForcesCentrifugal: outward force in circular motion
4 Centripetal Force: Can pushes on bug’s feet From our point of reference no centrifugal force b/c of absence of force and tendency to go in a straight line (inertia)Like when turning sharplyin a car… you want to staygoing straight that’swhy your body moves.
