Does it???

Question

does taking a step before serving a volleyball affect the volleyball distance?

Answer 1

It all depends on the timing. Sometimes it increases momentum, other times its just wasted movement

Answer 2

i guess

i take like 3 steps then a jump and just jump float the ball in, it's pretty good

my jump float is like a back row pike i guess, but i haven't perfected it yet so i miss most of the time like 60%

Answer 3

Yes, if you take a step you get more momentum into your swing which allows you to put a spin on the ball, like top spin.

you can do that standing but you don't get as much power or spin on the ball.

taking a step always helps. but if you are trying to do a light easy serve stand straight up. But if you can Jump serve because there is twice as many advantages as taking a step into it.

Hope that helped.

Answer 4

yes

Answer 5

As long as you hit the ball as you're stepping, the minimal amount of momentum created with the step would have a minimal effect on the distance the volleyball will travel.

Answer 6

Yes most definitely!

Simply put:

E = mc2 where m stands for rest mass (invariant mass), applies most simply to single particles with no net momentum. But it also applies to ordinary objects composed of many particles so long as the particles are moving in different directions so the total momentum is zero. The rest mass of the object includes contributions from heat and sound, chemical binding energies and trapped radiation. Familiar examples are a tank of gas, or a hot bowl of soup. The kinetic energy of their particles, the heat motion and radiation, contribute to their weight on a scale according to E = mc2.

The formula is the special case of the relativistic energy-momentum relationship:



This equation gives the rest mass of an object which has an arbitrary amount of momentum and energy. The interpretation of this equation is that the rest mass is the relativistic length of the energy-momentum four-vector.

If the equation E = mc2 is used with the rest mass of the object, the E given by the equation will be the rest energy of the object, and will change with according to the object's internal energy, heat and sound and chemical binding energies, but will not change with the object's overall motion).

If the equation E = mc2 is used with the relativistic mass of the object, the energy will be the total energy of the object, which is conserved in collisions with other moving objects.

Mass Velocity Relationship

In developing special relativity, Einstein found that the total energy of a moving body is



with v the velocity. (We are now using m0 to denote the rest mass.)

For small velocities, this reduces to



Which includes the newtonian kinetic energy, as expected, but also an enormous constant term, which is not zero when the object isn't moving.

The total momentum is:



The ratio of the momentum to the velocity is the relativistic mass, and this ratio is equal to the total energy times c2. The energy and relativistic mass are always related by the famous formula.

While this is suggestive, it does not immediately imply that the energy and mass are equivalent because the energy can always be redefined by adding or subtracting a constant. So it is possible to subtract the m0c2 from the expression for E and this is also a valid conserved quantity. Einstein needed to know whether the rest-mass of the object is really an energy, or whether the constant term was just a mathematical convenience with no physical meaning.

In order to see if the m0c2 is physically significant, Einstein considered processes of emission and absorption. He needed to establish that an object loses mass when it emits energy. He did this by analyzing two photon emission in two different frames.

Relativistic mass

Main article: mass in special relativity

After Einstein first made his proposal, it became clear that the word mass can have two different meanings. The rest mass is what Einstein called m, but others defined the relativistic mass as:



This mass is the ratio of momentum to velocity, and it is also the relativistic energy divided by c2. So the equation E = mrelc2 holds for moving objects. When the velocity is small, the relativistic mass and the rest mass are almost exactly the same.

E = mc2 either means E = m0c2 for an object at rest, or E = mrelc2 when the object is moving.

Also Einstein (following Hendrik Lorentz and Max Abraham) used velocity and direction dependent mass concepts (longitudinal and transverse mass) in his 1905 electrodynamics paper and in another paper in 1906. However, in his first paper on E = mc2 (1905) he treated m as what would now be called the rest mass. Some claim that (in later years) he did not like the idea of "relativistic mass.  When modern physicists say "mass", they are usually talking about rest mass, since if they meant "relativistic mass", they would just say "energy".

Answer 7

now but it gives the ball more power which makes it harder for the defender to control his pass.

Answer 8

Yes and no....Yes, but only if you're keeping the ball in front of you. If you're stepping under it, or so it ends up behind you that step is actually hurting you. However, if you toss the ball in front, taking the step will increase distance by allowing you to generate power with your body weight as opposed to just your shoulder.

Answer 9

Yes it gives you more momentum!

Answer 10

yes, it sure does!

it gives you more momentum so the ball will go farther and faster :)
