1) Multiple choice question While reading section 6.1 of the book, you learned that angular speed, ?ω rad/s, of a rotating object is related to the linear speed or simply speed, v m/s, with the equation ?=??v=rω , where r is the distance of rotating object from the center of rotation. You also learned that v is tangent to the circular path every moment as shown in the sketch. The equation ?=??v=rω, tells us that Picture is below a) Speed, v, of a rotating object could change even when angular speed, ?ω , is constant b) Speed, v, of a rotating object remains same if angular speed, ?ω , is the same c) r must be constant to use this equation d) All in the list 2)Multiple choice question According to the sketch of the free body diagram of the car moving on a part of a circular path on a flat road, the centripetal force necessary to keep the car on the path comes from Free-body diagram is below a) Static friction force b) Kinetic friction force c) Weight of the car d) Normal force on the car e) Newton’s first law of motion

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
