Section 13.3 & 13.4 Centripetal and Centrifugal Forces Physics Chapter 13 Section 13.3 & 13.4 Centripetal and Centrifugal Forces

Centripetal Force Centripetal 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 Force Center

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 Forces Centrifugal: outward force in circular motion

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 sharply in a car… you want to stay going straight that’s why your body moves.
