Velocity and acceleration are both important parts of motion, but they do different things.

Velocity

• Velocity is about speed and direction.
• You can think of it as how fast you are moving in a certain direction.
• In simple math, it is the change in position over time:
  $v = \frac{\Delta x}{\Delta t}$
• For example, if you're going east at 50 meters per second, that’s your velocity.

Acceleration

• Acceleration is about the change in velocity.
• It tells you how quickly you are speeding up, slowing down, or changing direction:
  $a = \frac{\Delta v}{\Delta t}$
• So, if you start at 20 meters per second and speed up to 60 meters per second, you are accelerating.

In simple terms, velocity answers "where and how fast" you are moving. Acceleration answers "how that speed changes."
