Yes. Even though its speed doesn't change, its velocity does change, therefore it is accelerating.
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 it is a horizontal straight line, it means the object is moving at constant velocity. If it is a sloped line, it means the object is accelerating.
If its slanted up its accelerating, if down its decelerating.
Acceleration is scientifically defined as a change in velocity, not an increase in speed. Thus slowing down, speeding up, or changing direction are all forms of accelerating. If one is moving at a constant speed, then the only way to accelerate would be to change direction.
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 velocity-time graph would show uniform acceleration of a moving vehicle as a straight line with a constant positive slope, indicating that the vehicle is accelerating at a consistent rate.
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.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
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.
yes
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
Yes. Even though its speed doesn't change, its velocity does change, therefore it is 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).
