Work, energy and power: JAMB Physics Past Questions and Answers

What the JAMB syllabus covers in Work, energy and power

Our summary: Work, energy and power, the world's energy sources and their effects, and solar and nuclear energy.

• Work, energy and power ((i) definition of work, energy and power; (ii) forms of energy; (iii) conservation of energy; (iv) qualitative treatment between different forms of energy; (v) interpretation of area under the force-distance curve.)
• Energy and society ((i) sources of energy; (ii) renewable and non-renewable energy e.g., coal, crude oil, sun, wind etc.; (iii) uses of energy; (iv) energy and development; (v) energy diversification; (vi) environmental impact of energy e.g., global warming, greenhouse effect and spillage; (vii) energy crises; (viii) conversion of energy; (ix) devices used in energy production.)
• Dams and energy production ((i) location of dams; (ii) energy production.)
• Nuclear energy
• Solar energy ((i) photoelectric effect; (ii) solar collector; (iii) solar panel for energy supply.)
