chemical energy
When a match is struck against the side of a matchbox and bursts into flames, the energy transformation that takes place is from mechanical energy (friction between the match and the matchbox) to heat energy. The friction generates enough heat to ignite the match head, causing it to catch fire and release energy in the form of light and heat.
When a match is struck against the side of a matchbox, mechanical energy is converted into thermal energy due to friction. The heat generated from the friction causes the match head to ignite and start the chemical reaction, releasing more energy in the form of light and heat.
When a match is struck, the friction between the match head and the rough surface converts mechanical energy into heat energy through the process of combustion. The heat energy then ignites the matchstick, releasing light and heat energy as it burns.
Potential energy
The energy processed by a matchstick in a matchbox is chemical energy stored in the match head that is released as heat and light when the match is struck and ignites.

Striking a match against a matchbox involves frictional force. This force is generated when the rough surface of the match head rubs against the striking surface of the matchbox, producing enough heat to ignite the chemicals in the match. The friction converts kinetic energy from the motion of striking into thermal energy, leading to combustion.

Transformation. Energy cannot be created or destroyed, only transferred between different forms. In this case, the kinetic energy of an object is converted into potential energy as the object moves higher against gravity.
The energy transformation that occurs when a person lifts a chair involves converting chemical energy from the food consumed into mechanical energy to move the muscles, which lifts the chair against the force of gravity.
In any energy transformation energy is preserved.
A change from one form of energy into another is called energy transformation.
The matchstick in a matchbox possesses chemical energy. When the match is struck, the chemical energy stored in the match head is converted into heat and light energy through a chemical reaction, leading to ignition.
The most common unintentional energy transformation is the conversion of mechanical energy into thermal energy through processes like friction, which occurs when two surfaces rub against each other and generate heat. This transformation is often seen in everyday activities such as walking, driving a car, or using electronic devices.
