ASSIGNMENT 4 2024
UNIQUE NO.
DUE DATE: 8 OCTOBER 2024

, Question 1

1.1 Forms of Energy

1. Kinetic Energy

Definition: Kinetic energy is the energy an object possesses due to its
motion. The amount of kinetic energy depends on the object's mass and
velocity.

Example: A moving car, a flying airplane, or a running person all have kinetic
energy. The faster an object moves, the more kinetic energy it has.

2. Potential Energy

Definition: Potential energy is the stored energy an object has due to its
position, condition, or configuration. It can be gravitational, elastic, or
chemical potential energy.

Example: A ball held at a height has gravitational potential energy. The
energy is released when the ball is dropped, converting into kinetic energy.

3. Thermal Energy

Definition: Thermal energy (or heat energy) is the energy that comes from
the movement of particles within a substance. The faster the particles move,
the higher the temperature and the more thermal energy the substance has.

Example: Boiling water on a stove, where heat is transferred from the stove
to the water, raising its temperature.

4. Chemical Energy

Definition: Chemical energy is stored in the bonds between atoms and
molecules. It is released or absorbed during chemical reactions.
