Physics notes:
• motion and retardation
1.Motion:
- Motion means the movement of an object from its position.
There are two types of motion:
- Uniform motion (speed remains the same)
- Non-uniform motion (speed keeps changing)
2. Speed and Velocity:
- Speed = distance/time (scalar quantity)
- Velocity = displacement/time (vector quantity)
3. Retardation (Negative Acceleration):
- When an object reduces its speed, it is called retardation.
- Example: The car is stopping after applying brakes.
