1. Increasing Speed (Positive Acceleration):
* Same direction as velocity: The object is moving faster in the same direction. Example: A car speeding up on a highway.
2. Decreasing Speed (Negative Acceleration or Deceleration):
* Opposite direction to velocity: The object is slowing down. Example: A car braking to a stop.
3. Changing Direction (Centripetal Acceleration):
* Perpendicular to velocity: The object is changing direction while maintaining the same speed. Example: A car turning a corner at a constant speed.
4. Changing Both Speed and Direction:
* A combination of the above: The object is both speeding up/slowing down and changing direction. Example: A rocket launching into space.
Key Points:
* Acceleration is a vector quantity, meaning it has both magnitude (speed) and direction.
* Acceleration is the rate of change of velocity, which can be either speed or direction or both.
* Even if an object is moving at a constant speed, it can still be accelerating if it is changing direction.
