Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.

It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".


Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.


Are you talking about the Illinois Particle accelerator? Well I think that it doesn't go at a constant speed but at a constant Acceleration, since it is accelerating and not staying at one speed is is therefor Constant Acceleration until they slowly work it up to almost the speed of light.




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.


Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.


constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.


Acceleration does not mean speeding up. It means any change in the speed or direction of the motion. A particle moving around a curve is constantly changing the direction of its motion, and that's called acceleration, regardless of whether or not the speed is changing.


Neither -- acceleration = 0 when the speed is constant. =========================


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.)


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.


No. Acceleration is constant. The effect of constant acceleration is speed that increases at a constant rate.


A particle moving with a constant velocity has no acceleration. Acceleration is the change in velocity over time. If the velocity is constant, there can be no acceleration. For you Calculus junkies, dv/dt (v is velocity) is acceleration, and will equal zero if v is a constant.


When the acceleration is at constant 0, then the velocity will be constant.


False If the acceleration is constant the speed increases. If the speed is constant the acceleration is zero.



Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.


Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant


A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.


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.


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.


Constant speed has no acceleration, whereas changing speed does.


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.
