3 cards from this section. Quick, good the night before a test.
What is angular displacement and its unit?
Think about the circular movement of objects.
Provide the formula for angular velocity.
Remember, it's about how fast something spins!
What unit measures angular displacement?
Think about how circular paths are measured.
True or False: Angular velocity is the rate of change of angular displacement.
Consider the definition of angular velocity.
A bicycle wheel rotates at 80 RPM. Calculate its angular velocity in rad/s and describe how this affects the speed of the bicycle.
Convert RPM to rad/s before determining the effect on linear speed.
A disc starts from rest and has a constant angular acceleration of 2 rad/s². Determine how long it will take to reach an angular velocity of 12 rad/s.
Recall the formula for angular acceleration to solve.
