QUESTION 1
Energy Basics [18 marks]
1.1 Define and explain the different forms of energy, providing real-world
examples for each. (Focus on the following forms of energy; Kinetic energy;
potential energy; thermal energy; chemical energy; electrical energy, light
energy, and sound energy). (14)
1.2 Discuss the concept of energy transformation, giving examples of how
one form of energy can be converted into another. (4)
1.1 Forms of Energy (14 marks)
Energy exists in various forms, and each form has unique characteristics
and real-world examples. Here's a breakdown of the key forms of energy:
1. Kinetic Energy
Kinetic energy is the energy an object possesses due to its motion. The
faster an object moves, the more kinetic energy it has.
Example: A moving car has kinetic energy because of its motion. Similarly,
a flowing river also demonstrates kinetic energy through the movement of
water.
2. Potential Energy
Potential energy is the stored energy an object has because of its position
or configuration. This energy has the potential to be converted into other
forms of energy.
, Example: A rock held at the top of a hill has gravitational potential energy
due to its elevated position. When the rock rolls down, this energy is
converted into kinetic energy.
3. Thermal Energy
Thermal energy (or heat energy) is the energy an object possesses due to
the motion of its particles. It’s directly related to temperature.
Example: A cup of hot coffee has thermal energy due to the fast-moving
molecules inside it. The warmth you feel from the coffee is this energy
being transferred to your hands.
4. Chemical Energy
Chemical energy is stored in the bonds between atoms and molecules.
This energy is released or absorbed during a chemical reaction.
Example: The energy stored in gasoline is chemical energy. When
gasoline burns in a car engine, the chemical energy is converted into
kinetic energy that moves the vehicle.
5. Electrical Energy
Electrical energy results from the movement of electrons through a
conductor, such as a wire. It is widely used in powering machines and
devices.
Example: A light bulb glows because electrical energy is used to heat the
filament, creating light energy. Batteries store chemical energy and release
it as electrical energy when connected to a circuit.
6. Light Energy
