Angular momentum – (to be written)
Kid versus conservation of angular momentum
What happens when a hamster in a wheel suddenly stops running?
Linear momentum translated into angular momentum
Angular momentum appears even in physiology (the study of how cells and organs interact to form a whole being, including skeletons, muscles, organs, etc.) For instance:
A cheetah’s tail provides an excellent example of torque and angular momentum in action.
With a simple clockwise flick of the tail, the cheetah’s body (in a response which conserves angular momentum) rolls in the anti-clockwise direction (and conversely).
This enables the cheetah to position its body mid-flight so that it is ready to turn the instant its feet make contact with the ground.
SAT Subject Test in Physics
Circular motion, such as uniform circular motion and centripetal force
2016 Massachusetts Science and Technology/Engineering Curriculum Framework
HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion is a
mathematical model describing change in motion (the acceleration) of objects when
acted on by a net force.
HS-PS2-10(MA). Use free-body force diagrams, algebraic expressions, and Newton’s laws of motion to predict changes to velocity and acceleration for an object moving in one dimension in various situations
Massachusetts Science and Technology/Engineering Curriculum Framework (2006)
1. Motion and Forces. Central Concept: Newton’s laws of motion and gravitation describe and predict the motion of most objects.
1.8 Describe conceptually the forces involved in circular motion.
