Maga Ram Patel from the Department of Renewable Energy Engineering at MPUAT University in Udaipur, India presented on the basic science of energy conversion. The presentation defined energy as the ability to do work and discussed the law of conservation of energy. It explained that energy can be converted between different states such as potential and kinetic energy, and covered various types of energy including thermal, chemical, electromagnetic, nuclear, mechanical, and others. The presentation emphasized that energy can be converted from one form to another through various processes in nature and technology.
What is technology
This document provides an overview of a lecture on the meaning and nature of technology. The lecture was presented at the University of Ilorin and covered various topics including:
- Defining energy and the different forms it can take, such as mechanical, electrical, chemical, and nuclear energy.
- Explaining the differences between kinetic energy, which is the energy of moving objects, and potential energy, which is stored energy.
- How one form of energy can be converted to another through different processes, such as explosions converting chemical energy to heat and light, batteries converting chemical to electrical energy, and food converting its chemical energy to kinetic energy in the human body.
- The first and second laws of ther

- Energy is the ability to do work and can take many forms such as kinetic energy, potential energy, mechanical energy, chemical energy, electrical energy, electromagnetic energy, thermal energy, sound energy, and nuclear energy.
- Energy can be converted from one form to another but is never lost or destroyed.
- Major sources of energy include the sun, coal, oil, gas, wind, water, food, and electricity with the sun being the largest overall source of energy.
Energy forms and_changes
The document discusses the different forms of energy including heat, chemical, electromagnetic, nuclear, mechanical, kinetic, and potential energy. It explains that energy can be converted from one form to another but cannot be created or destroyed, as stated by the Law of Conservation of Energy. Energy is defined as the ability to do work or cause change and can take many forms such as light, motion, sound, temperature, and stored energy.

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 2. What is Mechanical Energy? o Energy due to a object’s motion (kinetic) or position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!
- 3. Examples of Mechanical Energy
- 4. What is Electromagnetic Energy? o Light energy o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
- 5. What is Electrical Energy? o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy
- 6. What is Chemical Energy? o Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.
- 7. Examples of Chemical Energy
- 8. What is Thermal Energy? o Heat energy o The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.
