Best Answer

constant speed=0 acceleration

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

A body moving with constant speed in a circular path has acceleration changing at every point.

If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.

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.

The acceleration would be zero because the turtle is moving at a constant speed

-- "Acceleration" is any change of velocity.-- "Velocity" is a speed and its direction.-- "20 meters per second" is a speed, not a velocity, because it doesn't mention a direction.-- We don't have enough information to say anything about that car's acceleration.If, for example, it happens to be moving at a constant speed of 20 meters per secondon a circular track, then it has plenty of acceleration.

a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).

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.

A body moving with constant speed in a circular path has acceleration changing at every point.

This type of acceleration occurs when an object is moving around a circle at a constant speed. As the object moves around the circle, the direction of its velocity is constantly changing. This type of acceleration is called centripetal acceleration. The direction of the acceleration is toward the center of the circle. I hope this answers your question. A car traveling 25 MPH turns 30-degrees to the left without losing speed -- it has accelerated.

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.

No, acceleration is a change in velocity. When a cyclist is moving at a constant speed around a corner, the direction of their velocity changes but not its magnitude, so there is no acceleration in the direction of motion. There may be a centripetal acceleration towards the center of the curve to keep the cyclist moving in a circular path.

If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.

False. A body moving with uniform speed along a circular path is actually subjected to centripetal acceleration, which is directed towards the center of the circle. This acceleration is responsible for keeping the body moving in a curved path, even though its speed is constant. Uniform acceleration implies a constant change in velocity, which is not the case for circular motion at constant speed.

That is what happening in case of a body moving uniformly around a circular path. Its speed ie the magnitude of velocity remains the same but every moment its direction is changed due to the constant acceleration known to be centripetal acceleration.

Even though the person is moving at a constant speed, they are changing direction constantly as they go around the track. Since acceleration is defined as any change in velocity, and velocity includes both speed and direction, the person running on a circular track is experiencing acceleration.

Yes, the ball is undergoing acceleration even if it is moving at a constant speed. This is because its direction is changing as it moves around the circular structure, leading to a continuous change in velocity, which is a form of acceleration known as centripetal acceleration.

Circular motion involves an object moving in a circular path at a constant speed. The direction of the object's velocity is continuously changing, resulting in acceleration towards the center of the circle, known as centripetal acceleration. This acceleration is necessary to keep the object in its circular path.
