Define inertial reference frame.
A reference frame where an object at rest stays at rest, and an object in motion stays in motion with constant velocity, unless acted upon by a net force.
Define angular displacement.
The change in angular position, measured in radians.
Define angular velocity.
The rate of change of angular displacement, measured in rad/s.
Define angular acceleration.
The rate of change of angular velocity, measured in rad/s².
Define radian.
The angle where the arc length equals the radius of the circle.
Label the diagram illustrating angular displacement.
Arc Length: s, Radius: r, Angle: θ
Label the diagram illustrating the relationship between linear and rotational quantities.
Arc Length: s, Radius: r, Angle: θ, Linear Velocity: v, Angular Velocity: ω, Linear Acceleration: a, Angular Acceleration: α
What is an inertial reference frame?
A reference frame where an object at rest stays at rest, and an object in motion stays in motion with constant velocity, unless acted upon by a net force.
Define angular displacement (Δθ).
The change in angular position, measured in radians.
Define angular velocity (ω).
The rate of change of angular displacement, measured in rad/s.
Define angular acceleration (α).
The rate of change of angular velocity, measured in rad/s².
Define radian.
The angle where the arc length equals the radius of a circle.
