Reading- Circular MotionPg. 208 Section 7.1List four examples of Circular Motion:a.b.c.d.The rate at which a rotating object spins is called its _________________ ____________________.Angular velocity describes _________________________________________________________________________________________________________________________.The sign of angular velocity depends on ________________.Rolling motion: a rolling wheel has both ________________ and angular ________________.How are linear and angular velocities of rolling objects related to each other?An object undergoing circular motion has a velocity that is _______________________ to the circle. If an object whirling on a string were to break free, it would continue in a straight line. This is because of Newton’s _____ Law. What keeps an object in circular motion over your head?Centripetal acceleration always points towards the __________________ of the circle and is perpendicular to the _____________________.Write down the equation for centripetal acceleration and what each variable represents:A force that points towards the center of the circle and is perpendicular to an object’s motion is called _____________________________________________.Write down the equation for centripetal force and what each variable represents:Describe the effect of the Centrifugal Force:Is centrifugal force a real force? Yes/noYour body pushing against the car is a action/reaction force. (circle one)Pg. 215 Section 7.2Describe how newton came up with his theory of gravitation and explain the term “orbit”:Gravity is a universal force and any object with ____________ will exert a gravitational force on any other object with _____________.What two things does the strength of the gravitational force between to objects depend on?a.b.Write the equation for the law of universal gravitation and state what each variable represents:According to the universal law of gravitation, if the mass of an object doubles then what happens to the force?What is the value of the gravitational constant “G”?____________________________Define satellite:Define orbit: ................
