physics behind standing broad jumps?
97270
you need alot of starting veleocity to gain altitude and distance.  you need the proper trajectory (probably 45 degs) and strong legs.

Hold your arm out in front of you with your thumb pointed up and look at a distant building (or whatever). Now look at your thumb with one eye,and then the other, going back and forth between the two eyes. The thumb will appear to jump back and forth on the building. This is parallax. If you hold your thumb closer, the jump looks larger and if it is further away, the jump is smaller.\n\nThe same thing happens when you look at nearby stars (thumb) compared to much more distant stars (building) from different ends of the earth's orbit (eyes). The main difference is that the amount of the jump is very small since the star is so far away. It turns out that the angle of the jump is haved if the distance to the star is doubled. By knowing the size of the earth's orbit and the amount of jump, we can determine how far away the star is.

Tip: Standing Jump and Reach\nThe standing jump and reach:1-Start with feet shoulder width apart, body straight up and down.2-Squat slightly, explode upward, reaching toward a target or object.3-Take no steps before jumping again.4-Repeat for 1:00, rest 1:15, go again. Do 3 sets.\n \nTip: 90-Second Step Jump\n1-Stand at the side of the step, feet shoulder width apart. 2-Jump onto the step, quickly jump off step on other side.3-Repeat the process in the opposite direction.4-Begin at 30 seconds, and work your way up to 60 and finally 90 as you feel more comfortable. 5-Rest 15 seconds longer than you jumped, doing sets of 3.\nTip: Two-Foot Ankle Hops\nHere´s how to do the two-foot ankle hop:1-Stand with your feet shoulder width apart, your body straight up and down.2-Using only your ankles, hop continuously in place.3-Extend your ankles to the maximum range with each jump.4-Continue for one minute, rest 1:15, then go again. Do 3 sets.\nTip: Bleacher Sprints\nA good way to improve quickness and jumping ability is to utilize bleachers for running. This can be done on a small set or a large set. Beginners - may want to start on a small set and run up and done 3 times. Intermediate - needs to try to complete a large set of about 15-20 bleachers 3 times. Experienced - players need to complete a large set of bleachers of about 20+ bleachers, skipping every other step. Every level should take 30 second break and complete at least 3 sets.\nStart with a warm up, including a light jog, stretching, big arm swings and side-to-side movements for 10-15 minutes, and then move on to the plyometric routine.

dude, wtf is a jumping program?

I think their called jumpers.  Check out as seen on tv website.    It should be on there.

Two approaches that I can think of from a non-physicist.\n\n1. Simply a marker over how far back it physically recoils; or\n2. A spring scale fixed to a point that measures the peak force pulling back against it (you could also use a G meter if available).\n\nGood luck

How about the adding of Gravitational Potential Energy (GPE) and Kinetic Energy (KE) as an object falls in the air to demonstrate the preservation of energy?\n\nBefore it falls all energy is GPE, as it falls GPE is converted to KE until just before it hits the floor then it is all KE.

Assuming the population of the earth is 6 billion, and the average person weighs 70kg, that equates to 420 million tonnes (if I've done my maths correctly). If everyone stood on one side and jumped simultaneously, then nothing will happen as no weight would be lost from the earth.\n\nIf everyone had such springy powerful feet that they were able to jump to escape velocity (25000 mph) which means they won't come back down again, then that would cause a displacement in weight which would affect the earth.

Align your feet with one in front of you and one behind you. Bounce back and from foot to foot, with a rocking motion.\n\nMake sense?? It is easier demonstrated.

Remember the story of the man long ago who lifted a brand new baby cow.  He lifted it every day and when it was a full grown cow, he could still lift it.  I did something like that with my vertical leap (female over six feet tall). I just started leaping up onto taller and taller things. I'm a grandmother now and my "party trick" is I can stand flat footed on the floor and jump to the top of a table. It looks freaky, but, gosh, it's fun to do. Remember, whatever a monkey swinging around in a tree can do, humans can do, if we are in ultimate health and active.

Generally because you, the world and the air around you are all moving at the same speed, so as you jump up, the forward momentum from the planet rotating will carry you forward.\n\nIf you jumped high enough you might be able to loose momentum sufficiently to travel backwards (or at least land behind the spot from which you took off.

It's not a gimmick, it's an illusion , the same as the mtatlic hill, you're going down but it looks lie uoi are going backwards,something to do with physics, ask the physic' pro's for the deep, lengthy answer, they're good!

It is not effected to any significant degree.\n\nThe numbers used to do any calculations would absorb any effect which may occur.  For instance the mass of the Earth is about 5.9742 E24 kg.  But do you really think this is an exact number, no, it is just an estimate rounded off.  To try to use this value for the Earth's mass to try to calculate the effects of something so insignificant will not work too well.\n\nWhen you are standing on the Earth, you and the Earth together have a certain angular momentum.  When you jump, angular momentum must be conserved (its the law).  But now that your mass is rotating slightly farther out than it used to be, your angular momentum changes, there for the Earth's must change ever so slightly to compensate.\n\nIf you wanted "numbers and calculations", you did not specificy nearly enough information.

There is no buildup of kinetic energy.  You simply swing your arms to counteract the torque caused by throwing your leg forward.
