Lesson: Angular MomentumPhysics
In this lesson, we will learn how to calculate the angular momentum of an object as the product of the object’s moment of inertia and angular velocity.
Sample Question Videos
A mountain bike is traveling at 10 m/s when it jumps and the wheels lose contact with the ground. The mass of the bike’s front wheel is 750 g and the wheel’s radius is 35 cm. What is the angular momentum of the spinning wheel in the air at the moment that the bike leaves the ground?
A particle of mass 5.0 kg has position vector at a particular instant of time, . At the instant , the velocity of the particle with respect to the origin is .
What is the angular momentum of the particle at the instant ?
If a force acts on the particle at the instant , what is the torque about the origin at that instant?
An airplane of mass kg flies horizontally at an altitude of 10 km with a constant speed of 250 m/s relative to Earth. What is the magnitude of the airplane’s angular momentum relative to a ground observer directly below the plane?
