Key Differences
Dynamics involves the analysis of forces and their impact on an object's motion, considering aspects like velocity and acceleration. Kinetics, on the other hand, primarily deals with the rate at which chemical reactions occur and the factors that influence these rates, such as temperature, concentration, and the presence of catalysts.
Dynamic is a branch of physics that seeks to describe the relationship between motion and the forces affecting it, often using Newton's laws of motion as a foundation. Kinetic is a crucial part of physical chemistry and biochemistry, providing insight into reaction mechanisms and the energy changes that accompany chemical reactions.
Dynamics can be divided into two main categories: linear dynamics, which deals with objects moving in a straight line, and rotational dynamics, which focuses on objects that are spinning or rotating. Kinetics explores how and why chemical reactions proceed at specific rates.
