What's the difference between these three?

Are they all just different varities of how fast you're going or are there physical differences of when you're walking, jogging, and running? A different gait?

in terms of speed, running > jogging > walking. All three have differents gaits I'd say. Running is more of an all-out let's see how fast you can get from point a to point b, jogging is for general exercise, and walking is too but is obviously less stressful on a body.

Walking always has one foot on the ground. Jogging is you are airborne, as in no foot is touching the ground, running has a longer period of time that you are airborne (leaping over the ground) sort of.

aye, jogging and running are a series of small jumps. Jogging is typically aerobic; all the oxygen required can be gathered during respiration. Running is usually anaerobic; most of the energy comes from stored glycogen/glucose in the muscles. (I think it's glucose, not sure.)

You'll burn the same amount of calories by running a mile or walking a mile, the difference is that running takes a lot less time.

As said above, walking is one foot is always on the ground.

Jogging is where you're going fast enough that one foot is off the ground at any point. Also is strided heel-to-toe.

Running is faster jogging.

Sprinting is running in which your weight is on the toe of your foot. Real sprinting your heel rarely reaches the ground, only beginning to once you reach your top speed and begin to stride.

I don't know if that's true. I can break a sweat running a mile but I don't walking it. That extra energy required to go faster means I'm burning more calories.

Seaver

Time is not taken into the amount of work done in an equation. Calories use work in the calculation of a calorie. Hense running a mile and walking a mile you have the same amount of weight moved the same distance, so same amount of work done.

Yes you burn the same amount of calories running and walking a mile. You are thinking how worked up your body is while running as opposed to walking, but make sure to take into account it's over a much briefer period than walking is. In the end they equal out to the same amount burned, just walking does it much slower.

but running will have your metabolism boosted for a longer period after the workout has ended. at the end of the day, more calories will be burned if you run because of the elevated metabolism post-workout

cliche

I'm not so sure about running, but I know with water sports the power required to maintain a speed varies with the cube of the speed - ie double speed needs 8x the power. As the time taken will be 1/2, that still means you use 4x the energy to cover the same distance twice as fast.
Most of this comes from friction, which is the main resistance in water sports. In running, air doesn't offer nearly so much resistance so the energy use is more likely to be dominated by other (more constant?) factors.

From the journal of exercise physiology, this article:

From a metabolic perspective, the primary finding of this investigation was a constancy of the metabolic cost per distance (MBTC) to changes in running speed, which is in agreement with previous studies (1,2,3). The running speeds used in our study ranged from 2.33 m/s to 4.0 m/s which was within the range of speeds collectively examined in previous research (1,2,3)

This is true provided your heart rate is at the right level - you won't burn the same calories if you dawdle. In fact, you can burn more calories in a certain mid-range heart rate over the same distance than you will in a high range. Been a while since I read up on this, so can't recall the ideal heart rate for fat burning, but it's at a rate that you would expect to have at a fast walking pace rather than running.

A heart monitor helps you figure all this out. It's all about how hard you work. I also agree with the water cube analogy. You can drag ass along for a mile or get things going. Big difference. Plus, it takes a period of time to get the heart back to a slow speed.
