Distance is the measure of how far an object has traveled regardless of time, while time is the duration taken to cover that distance. When a body is moving with uniform velocity, the distance covered is proportional to the time taken to cover that distance.
If a car moving in a straight line travels equal distance in equal time no matter how small these distances may be, the car is said to be moving with a CONSTANT or Uniform Velocity.
The distance covered by an object in the last second of its motion is equal to the object's velocity in meters per second. This means that if the object is moving at a constant velocity, the distance covered in the last second will be the same as the velocity.
To find the uniform velocity, divide the distance traveled by the time taken. Velocity = Distance / Time Velocity = 602 m / 250 s Velocity = 2.408 m/s Therefore, the uniform velocity of the object moving 602 m East in 250 seconds is 2.408 m/s.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
A distance-time graph for an object moving at a constant velocity will be a straight line - the gradient of the line corresponds to the velocity. Non-uniform motion will cause the gradient of the line to change.
Uniform Constant Deceleration
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
For velocity to be truly uniform, the object must be moving in a straight line. If that is the case then the acceleration is Zero.
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.

Zero, since the velocity doesn't change.
