Study Notes
Motion
- Motion occurs when an object changes its position with respect to a reference point over a given time.
Description of Motion
- Mathematically described in terms of:
- Displacement
- Distance
- Velocity
- Acceleration
- Speed
- Measured with respect to a frame of reference and the change in position of the body over time.
Branches of Physics
Kinematics
- Studies the motion of objects without considering their causes.
- Focuses on describing the motion of objects.
Dynamics
- Examines the effect of forces on motion.
- Studies the causes of motion.
