Units & Measurements · Class 11

💡 Master the Principle of Homogeneity to quickly verify the correctness of any physical equation and to derive simple relations between physical quantities.

Kinematics · Class 11

💡 Always resolve the initial velocity into horizontal and vertical components and analyze motion independently in these two perpendicular directions using 1D kinematic equations.

Waves & Sound · Class 11

💡 Master the sign convention and remember that all velocities must be relative to the medium; resolve velocities along the line of sight for angled motions.
