The term you are likely looking for is non-uniform velocity.
Here's the breakdown:
* Uniform velocity: This means an object is moving at a constant speed in a straight line. There is no change in either speed or direction.
* Non-uniform velocity: This means an object is either changing its speed, its direction, or both. This could be a car accelerating, a ball thrown in the air, or a planet orbiting the sun.
Key takeaway: Uniform velocity is a special case where an object moves consistently without any change in its motion. Non-uniform velocity is the more general case where the object's motion can be changing.
