As you run circular laps at a constant speed, your speed remains constant, but your velocity changes because velocity is a vector quantity that includes direction. Your acceleration points towards the center of the circle, providing the centripetal force needed to keep you moving in a circular path.
What else can I help you with?
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.
Is a person running in a circular track at 7mph an example of constant velocity at zero acceleration and if so why?
Yes, a person running in a circular track at a constant speed of 7mph is an example of constant velocity and zero acceleration. While the person is changing direction, their speed remains constant, resulting in a steady velocity. Acceleration would only occur if there were a change in speed or direction.
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.
How is circular motion accelerated motion?
"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the velocity changes by definition, even if the MAGNITUDE of the velocity (also known as "speed") doesn't change.
Can a body have 0 velocity and still acceleration?
Yes, a body can have zero velocity and still have acceleration if its speed changes directions while its magnitude remains constant. This situation occurs when an object is moving in a circular path at a constant speed. The change in direction of velocity due to the circular motion results in centripetal acceleration.

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.

This situation occurs when an object is moving in a circular path at a constant speed. The change in direction of velocity due to the circular motion results in centripetal acceleration.
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
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.
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 is circular motion with constant speed called accelerated motion?
Acceleration is defined as change in velocity. Velocity is speed and direction. So when you're going round in a circle (circular motion), you're changing direction constantly, therefore changing velocity and therefore accelerating.
