Study Guide: Rotation

Assignments:

For the test over rotation, you should be able to:

• Express an anglular displacement in radians or revolutions
• Be able to convert from degrees to radians or radians to degrees
• State the number of radians in a full circle, half circle, or quarter circle
• Work with angular variables to solve kinematics equations
• Convert from linear to angular variables and from angular to linear variables
• Compare linear and angular velocities for two objects rotating together at different radii.
• Calculate rotary work and power
• Use rotational inertia to predict rotation rates
• Use Newton's 2nd law for rotation to calculate angular acceleration produce by a torque.
• Use conservation of energy to analyze rolling and calculate linear speed
• Describe precession and give an example
