Question

What is the difference  uniform and constant velocity ?Is acceleration zero in case of both constant and uniform velocity?

Charlotte Aaron · Accepted Answer

Refer to the explanation below.

UNIFORM VELOCITY: when an object is moving in a straight line, without any acceleration. No change in speed or direction is experienced. CONSTANT VELOCITY: when the speed of an object has not changed even though the object may have experienced a change in direction (zero acceleration). To answer the second half of your question: Yes, acceleration is zero for both uniform and constant velocity based upon these two definitions.

Leo Abeyta · Answer

There is no difference between the two expressions.

And it follows that the acceleration is zero.

undefined Great question! Let's break it down step by step:

1. **Definition of Velocity:**
   - Velocity is how fast an object is moving in a specific direction.
  
2. **Uniform Velocity:**
   - Uniform velocity means the object is moving at a constant speed in a straight line without any change in its velocity.
  
3. **Constant Velocity:**
   - Constant velocity is a specific type of uniform velocity where the object is moving at a consistent speed and in a consistent direction.

4. **Difference:**
   - The main difference is that all constant velocities are uniform, but not all uniform velocities are constant. In other words, constant velocity is a specific case of uniform velocity where there is no acceleration.
   
5. **Acceleration:**
   - In both cases of constant and uniform velocity, the acceleration is zero. This means there is no change in the speed or direction of the moving object.
  
In summary, both constant and uniform velocities involve no acceleration, meaning there is no change in speed or direction. The key distinction is that constant velocity specifically refers to a consistent speed and direction, while uniform velocity is a more general concept of steady motion.
