comparing to an atom , the particles of it are very very small , their
collision may be effective inside that atom but we could not measure the effectiveness since it takes place for a very very small time (fempto seconds) than the size of electron. Hence we think that the particle collisions are ineffective .
The contact between reactants is improved if the particle size is smaller..

the electron
It increases the number of high-energy collisions
It increases the number of collisions at the right orientation.
When the number of particle collisions increase the rate of chemical reactions also increase.
In order for heat to be conducted, there have to be collisions between atoms or molecules, in which energy is transferred from a faster moving particle to a slower moving particle. In a vacuum there are no particles, hence, no particle collisions and no heat conduction.
gas particle collisions are considered to be perfectly random.
Experts estimate that if a ring particle survived the age of the solar system it would undergo 49 collisions.
the number of particle collisions increases
the number of particle collisions increases
A hub creates the most traffic collisions.
Straight line
The answer will depend on whether or not there is any acceleration (linear or other) and whether or not particle collisions occur.
Head-on collisions are usually the most fatal ones.
More collisions between particles of matter means a faster reaction rate. When you increase the kinetic energy of a sample of matter, you increase the number of particle collisions, as well as the force with which they collide. This in turn increase the rate of reaction.
Gas particle collisions are generally modeled to be perfectly elastic (i.e., there is no change in the kinetic energy before and after the collision). This is very close to reality, since the gas particles have little internal structure which can undergo permanent deformation.
