Yes, it's acceleration will be zero because the velocity isn't changing, but it has an acceleration. Think of it in terms of integration and derivation. Acceleration is the derivative of velocity, so if velocity is a constant number the acceleration must be zero.
Generally if value of acceleration is "zero", we consider it to mean that there is NO acceleration. The question that was actually answered above was "Can acceleration be DEFINED fora body moving at constant speed?"
It is possible for an object to be moving at a constant angular speed and yet have an effective acceleration in a tangential direction.
===========================================
Both of you guys are missing the most important point here, with the result
that you have to twist your own arm almost to the point of dislocation in order
to state an answer.
The essential underlying consideration is that, contrary to popular misconception,
"acceleration" does not mean 'speeding up', or even 'changing speed'. It means
"change in velocity", and "velocity" means "speed anddirection". If either speed
or direction change, then that means there is 'acceleration'.
The answer to the question is simple, and almost entirely non-technical. It is:
"Yes, because 'acceleration' means change of either speed or direction. So, if
the direction of the body's motion is changing, then the body has acceleration,
even if its speed is constant."
The acceleration would be zero because the turtle is moving at a constant speed
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Constant speed means constant velocity. Constant velocity means an object is covering same distance in equal intervals of time. So how is it possible to have acceleration. Acceleration means speed is increasing with equal intervals of time. So its not possible according to my logic.
A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
A body moving with constant speed in a circular path has acceleration changing at every point.
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".
No, because acceleration is the rate of change of velocity.
Not possible, acceleration dV/dt =0.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
The acceleration would be zero because the turtle is moving at a constant speed
It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.
centripetal acceleration
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.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
If he is moving at a constant speed and not changing direction, then acceleration is zero.
