if an object is moving without any net force or acceleration, it is moving at constant speed, or constant velocity. For example a satellite orbiting the earth is moving at constant speed, a car traveling at 60 mph, a wind of 20 mph. etc.
A car moving at constant speed in a straight line is also moving at constant velocity.
A ball rolling at a constant speed at the same rate of speed on a still surface.
Photon or rather light
NO, all hings were not travel at constant things but some things r travel in constant speed for example solar system
Yes, it can. Perhaps the simplest example is when an object moves at constant speed, in a circle. In this case, the speed doesn't change; the velocity does.

constant
An example of an object being accelerated even though its speed remains constant is a car traveling down a hill. Even if the driver maintains constant pressure, the car will accelerate due to the incline of the hill.

No. The speed can be consant but direction can change and thus the velocity changes.
Exactly the same way that the speed can be constant but the distance keeps increasing.If the acceleration happens to be an increase in speed, then "constant" accelerationmeans that the speed will increase just as much in the 7th minute, for example,as it increased in the 4th minute, for example, etc.Acceleration can be the rate at which speed changes. So if the acceleration is constant,then the speed is changing at a constant rate.(Note: Acceleration doesn't have to be a change of speed. It can also be a changeof direction, at constant speed.)
constant velocity means the speed and direction are the same.
Photon or rather light
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
