In the context of angular displacement, what does the angle θ represent?
θ represents the angular displacement, the angle through which an object rotates.
In the context of angular displacement, what does the arc length 's' represent?
The arc length 's' represents the distance traveled along the circular path due to the rotation.
In the context of angular displacement, what does the radius 'r' represent?
The radius 'r' represents the distance from the axis of rotation to the point where the displacement is measured.
Define angular displacement.
The angle in radians through which an object rotates around an axis.
Define average angular velocity.
The rate at which angular position changes with time.
Define average angular acceleration.
The rate at which angular velocity changes with time.
What are the units for angular velocity?
Radians per second (rad/s).
What are the units for angular acceleration?
Radians per second squared (rad/s²).
Compare angular displacement and linear displacement.
Angular displacement: angle through which an object rotates | Linear displacement: change in position of an object in a straight line.
Compare angular velocity and linear velocity.
Angular velocity: rate of change of angular displacement | Linear velocity: rate of change of linear displacement.
Compare angular acceleration and linear acceleration.
Angular acceleration: rate of change of angular velocity | Linear acceleration: rate of change of linear velocity.
What is the difference between clockwise and counterclockwise rotation?
Clockwise: Typically assigned a negative value. | Counterclockwise: Typically assigned a positive value.
