Study Notes
Motion and Its Description
- Kinematics is the branch of physics that describes the motion of objects without reference to their cause.
- An object that is not in motion relative to a given frame of reference is said to be at rest.
- According to modern physics, it is impossible to determine the absolute motion of an object.
- The mathematical description of motion in terms of displacement, distance, velocity, and acceleration is called kinematics.
Force and Motion
- Dynamics is the branch of physics that studies forces and their effect on motion.
