Study Notes
Kinematics
- Kinematics is the branch of physics that describes the motion of objects without reference to their cause.
- It deals with the mathematical description of motion in terms of:
- Displacement
- Distance
- Velocity
- Acceleration
- Speed
- Frame of reference to an observer
- Motion is a continuous change in the position or configuration of a physical system in space.
- If an object is not in motion relative to a given frame of reference, it is said to be at rest.
- The concept of absolute motion cannot be determined, as there is no absolute frame of reference.
