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).
