Here's the breakdown:
* Position: Describes where an object is located in space.
* Velocity: Describes how fast an object is moving and in what direction. It's the rate of change of position over time.
* Acceleration: Describes how quickly an object's velocity is changing. It's the rate of change of velocity over time.
Think of it this way:
* Position: Imagine a car parked on a street. Its position is fixed.
* Velocity: The car starts moving. It now has velocity.
* Acceleration: The car speeds up or slows down. This change in velocity is acceleration.
Key takeaway: Acceleration is about the *change* in velocity, not the change in position itself.
