The Ethiopian Grade 11 Old Curriculum Physics textbook has 8 units, they are:
- Measurement and Practical Work
- Vector Quantities
- Kinematics
- Dynamics
- Work, Energy, and Power
- Rotational Motion
- Equilibrium
- Properties of Bulk Matter
Unit 1: Measurement and Practical Work
Students learn the fundamentals of scientific measurement, including units, significant figures, and the scientific method. They also study types of errors, precision, accuracy, and how to write clear experimental reports.
Unit 2: Vector Quantities
This unit introduces scalars and vectors, their representation, and how to resolve and combine vectors. Students also explore the scalar product and its applications in physical problems.
Unit 3: Kinematics
Students examine motion in straight lines and planes, including projectiles and circular motion. They learn to apply equations of motion, analyze graphs, and solve real-world motion problems.
Unit 4: Dynamics
The unit focuses on forces, Newton’s laws, friction, momentum, and collisions. Students also study centre of mass, uniform circular motion, and momentum conservation in variable-mass systems.
Unit 5: Work, Energy, and Power
Students explore the concepts of work, kinetic and potential energy, and the work-energy theorem. The unit covers energy conservation, power calculations, and transformations between different energy forms.
Unit 6: Rotational Motion
This unit introduces rotational dynamics, including torque, angular acceleration, and angular momentum. Students study rotational kinetic energy, moments of inertia, and the motion of rigid bodies.
Unit 7: Equilibrium
Students learn the conditions for equilibrium, including force and torque balance. The unit covers stability, coplanar forces, and the effects of couples on rigid bodies.
Unit 8: Properties of Bulk Matter
The unit covers elasticity, fluid statics and dynamics, and thermal phenomena. Students learn concepts like Young’s modulus, Archimedes’ principle, Bernoulli’s equation, heat transfer, and thermal expansion.
