Dynamics is simply a branch of Physics, generally comes under mechanics. Mechanics is the science of forces as well as motions. It involves a relatively small number of basic concepts such as force, mass, length, and time.
Dynamics considers the forces that affect the motion of moving objects and systems. Newton’s laws of motion are the foundation of dynamics. These laws provide examples of the breadth and simplicity of principles under which nature functions.
- A particle will remain at rest or continue with its motion unless acted upon by an external force.
- The force on an object is equal to its mass multiplied by its acceleration F =ma).
- Every action has an equal and opposite reaction.
- More simply known as F =ma, this is probably one of the most fundamental formulae in Dynamics. It’s one of those that pops up all over Dynamics and is a perfect idea to learn.
