Want this question answered?
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
A car going at a constant speed is not accelerating (its rate of acceleration is zero).
Yes. 'Acceleration' means either speed or direction is changing. If direction is changing,then there is acceleration, even if speed is constant.
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Straight line at a constant speed = no acceleration
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
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.)

Yes. Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
