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.
When you run around a track at 5 km/h your velocity is actually constant, if you keep the speed constant.
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.
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
Velocity=m m=rise/run
The frequency of the applied voltage is constant.
The key point is that the net force is zero. This is not the same as having zero force acting on it. The forces of drag and friction are always acting on moving objects, and the engine generates a force through the wheels that balances out this force, keeping you at a constant velocity. If the engine was stopped, this counterforce would no longer be in effect, and the unbalanced force of the drag would eventually slow the car to a stop.
sure.
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
No. If you can drive around a ten-mile track in the same time it takes you to drive around a one-mile track, then your angular velocity is the same in both cases. But in order to do that, you'll need much higher tangential velocity during the longer run. Tangential velocity is what you'd normally call your 'speed' as you blaze around the track.
60mph. slightly slower than the flying pig you were chasing.
u would have to run around the track once
You run around on a big track!
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
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.
Any child can run around a track as long as they can run. There is no age requirement to be able to go around a track. Kids 1-2 years old may run if they wish.
1 lap around track = 400 meters = 1/4 mile
i think that's 12 mph constant
