accelerating
You are most aware of motion in a moving vehicle when it is accelerating, as you can feel the change in speed more distinctly. When the vehicle is moving steadily in a straight line, the sensation of motion becomes less noticeable because your body has adapted to the constant speed.
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.
A particle moving in a straight line may or may not have acceleration. Acceleration is adifferent phenomenon altogether. the rate of change of velocity is acceleration, a particle can move in a straight line with a constant velocity thus having no acceleration & it can also move with increasing or decreasing velocities thereby accelerating or deaccelerating.
If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
If an object is not accelerating, it can exist in two other states of motion: constant velocity motion (moving with a steady speed in a straight line) or at rest (not moving at all).
Moving in the positive direction at an increasing speed. (Accelerating positively)

No, a body moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed of the body remains constant, there is no acceleration. For example, a car moving at a steady 60 mph on a straight road is not accelerating.
You would say that the object in motion is accelerating. Or you can say that the object's velocity is increasing.
A moving object with velocity and acceleration vectors in the same direction is accelerating in the direction of its motion. This means that its speed is increasing as it moves in a straight line.
