Study Notes

Types of Speed

Acceleration:
- Defined as the change in velocity over change in time.
- Occurs during speeding up, slowing down, or changing direction.
Velocity:
- Represents the speed of an object in a specific direction.
- Essential in understanding motion in a directional context.
Constant Speed:
- Describes a scenario where the speed does not change over time.
- Indicates uniform motion without acceleration.
Variable Speed:
- Refers to when an object's speed changes throughout its motion.
- Common in real-life scenarios such as driving through traffic.
Average Speed:
- Calculated by dividing the total distance traveled by the time taken for that travel.
- Useful for summarizing overall motion over a journey.
Instantaneous Speed:
- The speed of an object at a specific moment in time.
- Important for understanding speed variations during a motion.
