Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
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.
If an athlete runs once around a track back to the starting line is her average velocity zero?
Yes, the lazy bum has done no work at all.
Julie ran eight laps around her school's quarter-mile track in 18 minutes Her average velocity was?
You say the track is 400m, then ask how far you have run after 18 laps. Your distance is 2 miles. Your average speed is 9min per mile. apex- 0
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.)
Is velocity an objects speed and direction of motion?

What is the average weight for a 14 year old track runner?

The speed of an object in a paticular direction?
The speed of an object does not, by definition, have a direction. Speed is defined as the total distance that an object travels divided by the time that it takes the object to travel that distance. A similar concept which does have a direction is velocity. Velocity is defined as the displacement of the object (how far it has moved from its original position and the direction in which it has moved) divided by the time during which it moved. The difference between these two concepts can also be explained in terms of a runner completing a lap around a quarter-mile track. If it takes the runner three minutes to complete the lap, the runner's speed is .25miles/3minutes. The runner's velocity, however, is zero. This is because the runner starts at the same place that they end (because the track is a loop) so that at the end of the 3minutes they are back where they started which makes their displacement zero.
Emily jogs 3 laps at the track to warm up. she jogs at 5mph. then she runs 3 more laps at 7 mph. what is true about her average speed and her average velocity?
Her average speed is greater than her average velocity.
