Motionless objects and objects moving in a straight line with constant speed both have a constant velocity of zero or a constant velocity in a single direction, respectively. They share the characteristic of having a consistent position relative to a reference point over time.
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
The tendency of a moving object to keep moving in a straight line after the kinetic energy has run out is due to inertia. Inertia is the property of matter that causes objects to resist changes in their motion, so an object in motion will continue moving at a constant velocity in a straight line unless acted upon by an external force.
The tendency of objects in motion to stay in motion and objects at rest to stay at rest unless acted upon by an external force is known as inertia.
Without friction, moving objects will continue to move at a constant velocity in a straight line, as there would be no force to decelerate or stop them. These objects would essentially keep moving indefinitely unless acted upon by an external force.
It is called inertia.

light travels in a straight line because it can only be bend by reflective objects.

You are most aware of motion in a moving vehicle when it is accelerating because you can feel the change in speed or direction. When the vehicle is moving steadily in a straight line, the sensation of motion may be less noticeable as there are fewer changes occurring.
Some examples of types of motion include linear motion (objects moving in a straight line), rotation (objects spinning about an axis), oscillation (objects moving back and forth around a central point), and orbital motion (objects moving in a curved path around another object).
If an object's velocity-time graph is a straight line parallel to the time axis, then the object's acceleration is zero. This means that the object is moving at a constant velocity.
