I would say potential and kinetic true true
John Dalton studied hydrogen and oxygen, recognizing them as elements during his research on the nature of matter and atomic theory.
In a solid, energy is primarily stored in two forms: potential energy and kinetic energy. The potential energy arises from the arrangement and bonding of molecules or atoms within the solid structure, while kinetic energy is related to the vibrations of these particles around their fixed positions. Unlike liquids and gases, the particles in solids are closely packed and have limited movement, resulting in lower kinetic energy compared to other states of matter.
During gas particle collisions, kinetic energy is transferred between the particles. When two particles collide, one particle may lose kinetic energy while the other gains kinetic energy, depending on the relative masses and velocities of the particles involved. Overall, the total kinetic energy of the system remains constant due to the principle of conservation of energy.
When performing work, the two types of friction that are acting upon are static friction and kinetic friction. Static friction occurs when an object is at rest, preventing it from moving. Kinetic friction occurs when the object is in motion, resisting its movement.
Ancient Greeks had two major theories of matter. These were the Atomic theory of matter and the theory of pangenesis.

The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.

We generally think of kinetic energy as the energy of motion. And the two things that matter most as regards the energy of a moving object are its mass and its velocity.
Temperature and the mass of the particles are the two factors that affect the average kinetic energy of particles in any type of matter. As temperature increases, the average kinetic energy of particles increases as well. Additionally, particles with greater mass tend to have lower average kinetic energy at a given temperature compared to lighter particles.
The other two states of matter are liquid and gas. In the liquid state, particles have more kinetic energy compared to solids, allowing them to flow and take the shape of their container. In the gas state, particles have even higher kinetic energy and are able to move freely and independently.

Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. So this is collision theory again. You also need to discuss kinetic theory in an experiment where you vary the concentration. Although you keep the temperature constant, kinetic theory is relevant. This is because the molecules in the reaction mixture have a range of energy levels. When collisions occur, they do not always result in a reaction. If the two colliding molecules have sufficient energy they will react.
Gravitational Theory is the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The theory of Democritus and Leukippus was confirmed 2 400 years later; all the matter is...atoms. But note that the two Greek scientists created this theory intuitively, not after experiments.
The kinetic-molecular theory may be limited by high pressures where intermolecular forces become significant and affect gas behavior beyond simple particle motion. Additionally, at very low temperatures, quantum effects can come into play, causing deviations from classical gas behavior predicted by the theory.
