An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
When we say an object moves with constant speed, it means that the object is moving at the same rate without speeding up or slowing down.
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
its uniform.
Uniform.
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
The velocity increases at a constant rate.
Of course not, it depends on speed with which an object moves.
no
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
If an object moves in the same direction and at a constant speed for 4 hours, then the distance it travels will be equal to speed multiplied by time. The object's velocity will remain constant, and its displacement will be in the same direction as its motion.
Both are definitely zero
