Introduction to Particle Dynamics

In the previous topics we only talked about equilibrium in static, stationary objects. During this unit we will be talking about particle dynamics.

For the purpose of this unit, when I say the word "Particle" I am referring to an object that has a mass but no direction.

The Kinematics are the study of a position or displacement, velocity and acceleration without mentioning the agent responsible.

Kinetics, are the study of motion together with the agent responsible (Force/Movement).


Kinematics
A straight line motion (rectilinear motion)

Motion In a Curve

The motion in a curve originates from the radius of curvature, which is defined as rho. From this you can calculate the angles, normal accelerations, tangential acceleration, tension etc.
