1.1 Potential Energy
Potential energy refers to the stored energy in an object due to its position or state. Examples
include elastic energy in a stretched rubber band, or chemical energy in food and batteries.
1.2 Constellations
Constellations are star patterns in the night sky. Many ancient societies, including African cultures,
used them for storytelling, navigation, and agricultural planning.
1.3 Telescope
A telescope enables observation of faraway celestial objects. Galileo first used one in 1609 to study
the Moon, sunspots, and Jupiter’s moons, supporting the heliocentric theory.
1.4 Spectrometers
A spectrometer analyzes light to determine properties of celestial bodies, aiding in understanding
stars and other astronomical phenomena.
1.5 Circuit
An electric circuit is a closed loop with components like wires, a power source, and a bulb, allowing
current to flow and power devices.
1.6 Kinetic Energy
Kinetic energy is the energy an object possesses due to motion, such as a falling object or a
moving car.
1.7 Learning Theory
Learning theory encompasses concepts explaining how individuals acquire knowledge and skills
through experience or instruction.
1.8 Artificial Intelligence
AI involves machines mimicking human cognitive functions such as problem-solving,
decision-making, and pattern recognition.
1.9 Heat Transfer
Heat energy transfers from warmer to cooler objects via conduction, convection, or radiation.
1.10 Energy System
An energy system is a coordinated group of components that manage energy transformation and
transfer.
