Is an object going in circles at a constant speed an accelerated motion?
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
What is the difference between an object with constant acceleration and an object with constant speed?
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
What accelerates while traveling at constant velocity?
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
as direction is changing
Why does an object in uniform circular motion exhibits acceleration when its speed is constant?
Acceleration is defined as the change in velocity divided by the time ora = (vf - vi)/tVelocity measures the speed and the direction of an object.In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is considered accelerating. If this acceleration doesn't exist, the object would move in a straight line according to Newton's laws of motion.

Are satellites an example of acceleration as it orbits around the earth?
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

Can an object acceleration if its velocity is constant?
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
Why circular motion includes continuous acceleration even when the speed does not change.?
Acceleration involves a change in velocity. In the case you mention, the speed doesn't change, but the velocity does. The term "velocity" includes the direction of the movement, and the direction does change.
What is the acceleration of a car that moves at a constant velocity of 20 meters per second?
-- "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.

An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
Can a body moving at a constant speed have acceleration?
Yes. Acceleration is any change in velocity. Velocity is a vector quantity because it includes both speed and direction. Speed is a scalar quantity and does not include direction. Therefore, if your motion is changing direction, then you have a changing velocity regardless of your speed. And a changing velocity means you have acceleration.
Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
as direction is changing
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
