Physics – Secondary Grade 2

Course highlights

• Distinguish fundamental and derived quantities, use SI base units and measuring tools, derive dimensional formulas and SI units of derived quantities, check equations dimensionally and estimate measurement errors
• Describe straight-line motion, draw and interpret displacement–time and velocity–time graphs, distinguish kinds of speed and velocity, and use acceleration and the equations of uniformly accelerated motion (incl. free fall)
• State and apply Newton's three laws, explain inertia, and use momentum and F = ma in everyday situations
• Use density and relative density (with medical examples), distinguish streamline from turbulent flow, apply the continuity equation (A₁v₁ = A₂v₂) and the flow rate, and explain and calculate viscosity
• Calculate pressure at a point in a liquid (P = Pa + ρgh), measure relative density with a U-tube, explain the barometer and manometer and pressure units, and apply Pascal's principle to the hydraulic press
• Explain Brownian motion and apply Boyle's law, Charles's law and the pressure law, deduce absolute zero, and solve problems with the general gas law
• Calculate work (W = F d cos θ), kinetic and potential energy and power, and apply the conservation of mechanical energy
• Describe simple harmonic (oscillatory) motion – amplitude, period, frequency – and wave motion (transverse and longitudinal), and use v = f λ
• Apply the laws of reflection and refraction (refractive index, Snell's law), explain interference and diffraction (Young's experiment), total internal reflection and the critical angle, and deviation in a prism with minimum deviation
• Describe uniform circular motion and calculate centripetal acceleration and force in everyday situations
• Apply Newton's law of universal gravitation, find g at a planet's surface, and calculate the orbital speed and period of a satellite
