Here's what that means:
* Constant Velocity: The object moves at a constant speed in a straight line. This means its velocity (speed and direction) doesn't change.
* No Acceleration: Since the velocity is constant, the object is not accelerating. Acceleration is a change in velocity over time.
Examples of Uniform Motion:
* A car driving at a steady 60 miles per hour on a straight highway.
* A ball rolling across a smooth, level surface at a constant speed.
* A satellite orbiting Earth at a constant speed and altitude.
Important Note: In real-world scenarios, true uniform motion is difficult to achieve perfectly. There will always be some slight variations in speed or direction due to factors like friction, air resistance, or gravitational forces. However, many objects can be considered to be in approximately uniform motion for certain periods.
