Tangential acceleration - Study guides, Class notes & Summaries

Consider two children sitting on a merry-go-round, with one closer to the outer edge and one closer to the center. Which child has a greater angular speed? Correct Answer - They both have the same angular speed. The outside child would move a larger distance each rotation, so his linear speed would be larger but we are asking about angular velocity. There are two kinds of acceleration that can occur in rotational motion - tangential and centripetal. What best describes the difference betwee...

Units of G = N∗m²/kg² Correct Answer Force of Gravity Between Two Objects Correct Answer Kinetic Friction Correct Answer Static Friction Velocity vector is constantly changing and is tangential to the circle of motion Correct Answer Uniform Circular Motion - Velocity The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves. Correct Answer Centripetal Acceleration Correct Answer Centripetal Force θ = angle...

AP Physics Exam Questions and Correct Answers Latest Update 2024 Already Passed A circular platform of radius 2.0 m is initially spinning with an angular velocity of 8.0 rad/s. The angular velocity is then increased to 10. rad/s as the platform accelerates through 4.0 rad. Assume that the angular acceleration is constant. What is the magnitude of the angular acceleration of the platform? - Answers 4.5 rad/s^2 The an object that has rotated through an angular measure of 115° has an angular di...
