Mechanics : the branch of physics concerned with the motion of bodies in a frame of reference
Dynamics : the branch of mechanics concerned with the forces that cause motions of bodies
- Newtonian Dynamics : targets the movement of objects significantly slower than the speed of light
- Relativistic Dynamics : targets the movement of objects moving at near the spped of light such as a vehicle,
vessel, avion etc.
| Kinetics | Kinematics |
| Studies the cause for the motions of the object | Studies the position, acceleration and speed of an object |
| The mass of the object is taken into consideration | The mass of the object is not taken into consideration |
| Force is considered | Force is not considered |
| It does not involve any mathematical expressions | It involves mathematical expressions |
- Formula
| Ff=friction Fg=gravitational force  left equation : Kinetics right equation : Kinematics |
