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) QUESTION 2
Renewable and Non-Renewable Energy Sources [18 Marks] 2.1
Compare renewable and non-renewable energy sources in terms
of availability, environmental impact, and sustainability. (6) 2.2
Provide three examples of renewable and non-renewable energy
sources. (6) 2.3 Discuss three environmental impacts of
renewable and non-renewable energy sources. (6) 4
Here’s a detailed response to your questions on energy basics
and the comparison of renewable and non-renewable energy
sources.
QUESTION 1: Energy Basics
1.1 Different Forms of Energy
, Energy manifests in various forms, each with unique
characteristics and applications. Below are the different forms of
energy along with real-world examples:
1. Kinetic Energy:
o Definition: Kinetic energy is the energy of an object
in motion. It depends on the mass and velocity of the
moving object.
o Example: A car driving down the highway or a person
running. For instance, a car traveling at 60 km/h
possesses kinetic energy that can be calculated using
the formula KE=12mv2KE = \frac{1}{2}
mv^2KE=21mv2, where mmm is mass and vvv is
velocity.
2. Potential Energy:
o Definition: Potential energy is stored energy based on
an object’s position or state. It has the potential to be
converted into kinetic energy.
o Example: A rock perched at the top of a cliff has
gravitational potential energy. When it falls, that
potential energy is converted into kinetic energy as it
accelerates toward the ground.
3. Thermal Energy:
o Definition: Thermal energy, or heat energy, arises
from the internal motion of particles within an object.
It is the total energy of all particles in a substance.
o Example: Boiling water in a kettle produces thermal
energy, which can be felt as heat. The higher the
temperature, the greater the thermal energy present.
4. Chemical Energy:
