Conservation of Energy, Power and Efficiency
Energy changes form but never disappears, and power is how fast that change happens.
What this unit covers
Unit 5: Work, Energy, Circular Motion and Gravitation
- 1 Work and EnergyIn physics you only do work when a force moves something. Holding a heavy bag still does not count. · 10 min
- 2 Conservation of Energy, Power and EfficiencyEnergy changes form but never disappears, and power is how fast that change happens. · 10 min
- 3 Circular MotionA keke rounding a bend is accelerating even at a steady speed. Here is why, and what pulls it inward. · 10 min
- 4 GravitationThe same force that drops a mango in Benue keeps the Moon in its orbit and the satellites above Nigeria in theirs. · 14 min
