  2. Acceleration is classified based on its direction relative to velocity as positive acceleration (same direction as velocity), negative acceleration (opposite direction to velocity), or centripetal acceleration (perpendicular to velocity, in circular motion).

  3. During non-uniform motion, an object's velocity changes over time, meaning it can increase, decrease, or change direction. The rate of these changes varies, resulting in variable acceleration.

  4. In uniform motion, the change in velocity for an object over any time interval is zero, as the object maintains a constant speed and direction.
