IB DP PHYSICS 2025 SL&HL – Study notes- All Topics

Topic 4.1 Kinematics of rotational motion

Topic 1 Weightage : XX

Notes for 4.1 Kinematics of rotational motion – Only for Higher Level (HL)

torque τ of a force about an axis as given by τ = Fr sin θ, rotational equilibrium, unbalanced torque, angular acceleration, angular displacement, angular velocity, equations of motion for uniform angular acceleration, moment of inertia, Newton’s second law for rotation, angular momentum, resultant torque, kinetic energy of rotational motion

Graphical Analysis of Velocity and Acceleration

Slope \(=\frac{\Delta x}{\Delta t}=\frac{+8 \mathrm{~m}}{2 \mathrm{~s}}=+4 \mathrm{~m} / \mathrm{s}\)

Slope \(=\frac{\Delta v}{\Delta t}=\frac{+12 \mathrm{~m} / \mathrm{s}}{2 \mathrm{~s}}=+6 \mathrm{~m} / \mathrm{s}^2\)
