What are the differences between inertial and non-inertial frames of reference?
Inertial: Newton's laws hold true, non-accelerating | Non-inertial: Newton's laws don't apply, accelerating or under strong gravity.
What is the difference between rotational velocity and rotational acceleration?
Rotational velocity: How fast an object is rotating | Rotational acceleration: How quickly the rotational velocity changes.
Differentiate between a vector and a scalar quantity.
Vector: Has magnitude and direction | Scalar: Has only magnitude.
What are the key differences between inertial and non-inertial frames of reference?
Inertial: Newton's laws hold true, non-accelerating. Non-inertial: Newton's laws don't apply, accelerating.
Differentiate between scalar and vector quantities.
Scalar: Magnitude only. Vector: Magnitude and direction.
How do you convert degrees to radians?
Multiply the angle in degrees by π/180.
What is the formula for calculating tangential velocity (v) given rotational velocity (ω) and radius (r)?
v = ωr
What is the formula for calculating tangential acceleration (a) given rotational acceleration (α) and radius (r)?
a = αr
How do you calculate rotational velocity (ω) from change in angle (Δθ) and change in time (Δt)?
ω = Δθ/Δt
How do you calculate rotational acceleration (α) from change in rotational velocity (Δω) and change in time (Δt)?
α = Δω/Δt
How do you calculate angular velocity (ω) in terms of period (T)?
ω = 2π/T
