In this model we imagine particles as objects that are hard, have mass, and move according to Newtonian Mechanics.
Example: A Snooker ball, in a Snooker table we can compare each snooker ball to an individual particle.
Particle model is important because we can apply them to the microscopic world, like:
1. Electricity: Use to define the flow of electrons
2. Gases: Use to define kinetic theory
3. Solid: Use to define crystalline materials
4. Radio Activity: Nuclear model of the atom
5. Chemistry: Atomic Structure
Particles show two characteristics:
To get better understanding think of the waves we see in the Ocean. It is a flow of energy. The flow goes up and comes down and gradually decreases in size as it goes far from the source.
1. Waves are a way in which energy is transferred from one place to another.
2. In a wave, things change in a regular way, while energy flowing happens side by side.
3. If a wave is in up and down motion, energy is transferred horizontally.
It’s is used while defining:
a. Sound - (Pressure/density)
b. Light – (electric/ magnetic field strength)
c. Waves on a string
