Every time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time.

Select the situation below that would produce an average velocity of zero.?
A dog running in circles, stopping where it started
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 it possible for an object to be accelerating even after it has stopped moving?
Yes, a object can still be accelerating when the speed is zero, a classic example of which is throwing a ball straight up in the air, at the top of its trajectory it has an instantaneous velocity of zero while it is still accelerating towards the ground.
Why is the acceleration vector is always at 90 degrees to the velocity vector?
That's only true when the object is in circular motion.The circular motion is the result of a force (which produces acceleration)that's always perpendicular to the object's velocity.Like the gravitational force between the Earth and a geostationary satellite,or the tension in the string of a yo-yo that's doing circles.
Is swinging your arms around in circles very quickly an example of centrifugal force?
Swinging your arms around in circles very quickly is an example of centrifugal force.

What describes coplanar circles that intersect in exactly one point?
Tangential circles.
Describes two or more circles on the same plane that share the same center?
concentric circles
Are radii of congruent circles equal?
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.
What is an object that has traveled a certain distance but has no velocity?
a car or any automotive going in circles, it has no direction 8)
What describes the crust where the yellow areas of the two circles are falling?
convergent plate boundary. :)
This describes two or more circles on the same plane that share the same center?
concentric circle
What object has velocity?
Any object which moves has velocity.Velocity is a vector quantity which includes direction so the object's velocity will change at every point in time if there is a nonzero acceleration.An object going around in circles uniformly will have a zero average velocity when measured as displacement over a time interval if the time interval is a multiple of the period of revolution. Speed is similar to velocity but is a scalar quantity independent of direction; you can think of it as distance covered traveling per unit of time; that is what your speedometer measures.
What is the word that describes precise shapes or forms such as circles squares or triangles.?
They are geometric shapes called polygons

Which of the schematic drawings best describes a solution of li2SO4 in water water molecules not shown for simplicity?
Diagram C, or the diagram that has more Li ions (circles with the + sign in them) than the SO4 molecules (circles with the 2- sign in them).
