2 cards from this section. Quick, good the night before a test.
Define angular displacement in your own words.
Think about the angle measure.
What is the unit of angular velocity?
Consider the time taken for a full rotation.
What is angular velocity defined as?
Think about how we measure 'how fast' something spins.
Which equation relates angular acceleration and torque?
Look for the equation that shows how torque influences rotation.
A flywheel starts from rest and accelerates uniformly at 3 rad/s² for 5 seconds. Calculate the angular velocity and the angular displacement during this time.
Break it down using our angular kinematics equations.
A disk with moment of inertia of 0.5 kg m² is subjected to a torque of 10 N m. What will be the angular acceleration?
Remember the relationship between torque, moment of inertia, and angular acceleration.
