Which describes average velocity of a uniclycle going around in circles?
Every time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time.
Can the average velocity of a moving body be zero. state example?
Yes, if, for example, a car races around a circuit, its total displacement is zero and so its velocity, at the end of every lap, is zero.
Is the velocity constant if a car is going around a curve?
NO,velocity changes.
When Mike ran ten laps around his school's 14 mile track in 15 minutes. what was his average velocity in miles per hour?
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.

What is planetary velocity?
Orbital velocity is the average velocity (or speed) of a planet as it orbits around the sun. It is usually expressed as km/s or mph.
Jake and Brenda drove at a speed of 30 mph for 1 hour Then they turned around and drove 45 mph until they were back where they started What is true about their average speed and average velocity?
their average speed is greater than their average velocity.
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
Wind
Jake and Brenda drove at a speed of 30 mph for 1 hour. Then they turned around and drove 45 mph until they were back where they started. What is true about their average speed and average velocity?
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
Average mile time for college athlete?
a good athlete keeps there mile around 6 minutes....U of W hockey team runs two in twelve
How much do athlete earn?
Depends on the sport. But generally, very well. I believe the average for basketball is around $5million.
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 physical quantity is calculated by the slope of distance time graph?
The radial velocity ie velocity towards or away from your starting point. It is NOT the ordinary speed or velocity because you can run in a circle around your starting point at top speed but the distance will not change so the slope of the distance time graph will be zero.
What is the average pay of professional athletes in the US?
the average amount a pro athlete makes a season is around $29,450 (not evryone can be lebron james and make $20 million)
What is the average starting salary for a massage therapist for small animals?
the average salary is around £67,000.
Can the average velocity of a moving body be zero. state example?
