Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction.
That being said, you can accelerate an object without changing its speed by simply changing its direction.
A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
No, an object moving at a constant speed does not have acceleration. Acceleration is the rate of change of an object's velocity, so if the object is moving at a constant speed, its velocity is not changing and therefore there is no acceleration.
the question is very simple.no a body does not have acceleration when it is moving with constant velocity ,because a body posses acceleration when its velocity is not remain conserved or constant.yes if a body have constant speed it may have acceleration but not in case of constant velocity.
Because 'acceleration' means any change of the speed or the direction of motion.
Even if only the direction changes, that's technically an acceleration, and on a
circular path, the direction is always changing.
An object travelling at a constant velocity will always require acceleration to sustain an equilibrium against opposing forces, such as gravity, friction, wind speed, etc. If something at constant speed stopped accelerating, it would start to decrease under opposing forces.
Yes. Acceleration is defined as a change in velocity, and velocity is a measure of speed AND direction. Maintaining a constant speed while rounding a corner is an example of acceleration.
In the case of circular motion - an object can have constant angular speed and experience constant linear acceleration.
How can you even ask that. The words 'constant speed' and 'accelaration ' are a contradiction in terms.

What are the assumptions used to develop the kinematics model of circular motion?
The main assumptions in developing the kinematics model of circular motion are that the object is moving along a circular path at a constant speed, which implies uniform circular motion. Additionally, it is assumed that there is no tangential acceleration, meaning that the speed of the object remains constant. Finally, the assumption is made that the object's motion can be described using angular quantities such as angular displacement, velocity, and acceleration.
Can a body moving with uniform speed have variable velocity?
No, if an object is moving with uniform speed, its velocity must also be constant. Velocity is a vector quantity that takes into account both the speed of an object and its direction of motion. If the speed is constant, then the velocity must also be constant in both magnitude and direction.
When can an object a constant speed but not a constant velocity?
An object can move at a constant speed but not at a constant velocity when its direction is changing while its speed remains the same. This can happen if the object is moving in a circular path or if it is changing direction at irregular intervals. Constant speed refers to the magnitude of velocity remaining constant, while velocity includes both speed and direction.
What would be the shape of speed time graph of a body moving with variable speed?
The shape of the speed-time graph for an object moving with variable speed would depend on how its speed changes over time. It could be linear if the speed changes at a constant rate (acceleration or deceleration), curved if the acceleration is not constant, or a combination of different shapes if the speed fluctuates.
Is it possible to have a changing velocity and a constant speed?
No, velocity includes both speed and direction. If the velocity is changing, it means either the speed, the direction, or both are changing. Constant speed means the object is moving at the same rate without speeding up or slowing down.
Why is an object moving in a constant speed undergoing?
An object moving at a constant speed is not undergoing acceleration because acceleration is a change in velocity over time. Since the object's speed is not changing, there is no acceleration.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
Can an object be moving if acceleration is zero?
Yes, an object can be moving if its acceleration is zero. If the object is moving at a constant velocity, the acceleration will be zero even though the object is in motion.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
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.
What kind of speed has no acceleration?
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
What is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
Can an object that move at a constant speed be accelerating?
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
What is the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
The direction of acceleration of an object moving on a circular path at constant speed is pointed towards the center of the circle. This acceleration is called centripetal acceleration and is necessary to keep the object moving in a curved path.
When the velocity of a moving object stays the same it has a?
When the velocity of a moving object stays the same, it has a constant speed.
An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.
