The average velocity of a unicycle going around semicircles would be zero if it starts and ends at the same point, since the displacement is zero. If it starts and ends at different points, the average velocity would depend on the total distance traveled and the time taken to complete the semicircles.

What is average velocity?
Average velocity is defined as the change in position of an object divided by the time taken to undergo that change. It gives a measure of how fast an object is moving in a particular direction over a given time interval. Mathematically, it is represented as: average velocity = (final position - initial position) / time.
Is Average velocity the slope of the line tangent to the curve on a velocity time graph at a specific instant of time?
No, average velocity is the total displacement divided by the total time taken. The slope of the tangent to the curve on a velocity-time graph at a specific instant of time gives the instantaneous velocity at that moment, not the average velocity.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Would a radio controlled car produce an average velocity of zero?
For the purposes of this explanation, velocity will be given in m/s. If it's starting position is the same as its stopping position, the radio controlled car will have an average velocity of zero meters per second. This is because average velocity is displacement/time interval. Displacement is change in position and is a vector quantity, which has magnitude and direction. Average velocity is the displacement/time interval, and is also a vector quantity, including the magnitude of the speed and its direction. If you start and stop walking at the same position, your displacement is 0m, even if you walked a distance of 100 miles, and your average velocity would be 0m/s. Refer to the related link below for an illustration.
Can the average velocity of a particle be zero but not its average speed?
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
Which describes average velocity of a uniclycle going around in circles?
The average velocity of a unicycle going around in circles is zero because it returns to its starting point over a full revolution, resulting in no overall displacement. However, the unicycle's speed may vary as it accelerates and decelerates during each rotation.
Which describes the average velocity of a bicycle going at a constant speed in a constant direction?
Every time the unicycle returns to its starting point, the average velocity equals zero. C. The total displacement divided by the time.
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
Which equation describes how the average velocity of a moving object relates to its displacement?
The average velocity of a moving object is defined as the displacement divided by the time taken to cover that displacement. Mathematically, average velocity is equal to the change in position over the change in time: Average velocity = (final position - initial position) / time elapsed.
Which describes the average velocity of a bicycle going at a constant speed in constant direction?
The total displacement divided by the time. The slope of the displacement vs. time graph.
Why rms velocity is taken instead of mean velocity?
RMS velocity is used to characterize the average velocity of molecules in a gas because it accounts for both the speed and direction of particles. Mean velocity, on the other hand, only describes the overall average speed of particles without considering their directions. RMS velocity gives a better representation of the kinetic energy and behavior of gas molecules.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
What is the distance an objects moves divided by the time it took to move that distance?
This describes the average speed. If there is a direction specified that the distance has moved, then it will be a vector, and called average velocity.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
When is the average velocity equal to average of velocity for an object?
Always.
Is instantaneous velocity a vector or a scalar?
Instantaneous velocity is a vector quantity because it has both magnitude and direction. It describes the rate at which an object changes its position in a specific direction at a given moment in time.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
