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.
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.
How do you convert degrees to radians?
radians = (degrees * π) / 180
How do you calculate angular displacement?
Δθ = θ_final - θ_initial
How do you calculate angular velocity?
ω = Δθ / Δt
How do you calculate angular acceleration?
α = Δω / Δt
How do you relate angular velocity to frequency?
ω = 2πf, where f is the frequency in Hz.
