Lesson: Rotational Kinematics High School PhysicsPhysics
In this lesson, we will learn how to model the change of the position with time of objects that move along circular paths.
Sample Question Videos
A car drives repeatedly around a roundabout. The car has a constant angular velocity of 1.4 rad/s. What is the period of the car’s circular motion?
A helicopter flies in a circle of radius 375 m, taking a time of 42 s to complete one revolution. What is the magnitude of the acceleration of the helicopter toward the center of its circular path?
An angular displacement of is equal to an angular displacement of 7.25 rad.
