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.

∙ 11y agoYes, but only briefly, not permanently.
At an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time.
An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.

∙ 9y agoAcceleration 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.

∙ 9y agoYes. If the velocity doesn't change, there is zero acceleration.

Can it be possible that a particle have constant speed must have zero acceleration?
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".
Can a body moving with constant speed has acceleration?
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.
Can an object have a speed of 0 while it has an acceleration that is not 0?
Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.
When acceleration is 0 why does velocity have to be at a maximum?
It doesn't. If acceleration is zero, that just means that velocity isn'tchanging ... the motion is in a straight line at a constant speed.
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum

Its acceleration is zero, which is constant
Can a particle with constant speed be accelerating what if it has constant velocity?
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.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Can particle have zero speed and non zero velocity?
No.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
What can be said about the speed of a particle if the net work done on it is zero?
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Does a dish resting on a table have constant acceleration?
An object at rest has zero speed and zero acceleration.
