New contest: Capturing Kinetic Energy - Now Closed

[topdog]

One per entry makes sense. Sorry about entering two, I saw that others had done so and I did not know the rules. BTW, how do you delete an entry? Also, some of my posts have locks on them so they cannot be modified. I never checked the lock box, so how does that happen? Sorry if the questions are inappropriate, but I am new to posting on these wonderful, but a bit confusing to me, boards. And while I am at it, how do you put the [applaud] [smite] by your identity? And when you click on them, what happens? I'm done now

OK easy one first - you don't have applaud/smite against your own name (why would you want to smite yourself ? .

I see you have two posts in this section - the duck and the damselfly. I'm not sure why they appear as locked to yourself, but let me know which one you wish to leave in and I can remove the other.

[topdog]

Paul, can you remove the mallard.jpg and leave the damselfly.jpg please. Thank you

i thought i'd post this here since it's a moving car in the dark with a relatively slow shutter speed

[PhilD73]

Here's one from me:


Obviously the idea here was to use a relatively low shutter speed to capture a car (or truck of some kind, in this case) as the tyres picked up water, which produced an interesting pattern. The road was stationary and grounded the photo.

(please be aware I'm on holiday from 1st to 14th October, so won't be online for a while..)

Wow...lots of very nice entries here! Well done to everyone!

Is the contest over?

[mikej]

Although there are some nice shots here, I think people are getting "Motion" mixed up with "Kinetic Energy". Kinetic energy, the way I understand it, is the transfer of energy from one object to another... which does need force or motion, but motion by itself is not a display kinetic energy. For instance, a bowling ball hitting the pins is a display of kinetic energy, the ball going down the lane towards the pins would not be. The cue stick hitting the cue ball or a cue ball hitting another pool ball would be, the cue ball rolling across the table would not be. A keyboard hitting the wall would be, a keyboard flying through the air wouldn't.

That's my opinion about it anyway. But there are some nice motion shots in the group.

Oh dear, so I should have left my Mallard rippling the water in the contest! What do I know from kinetic energy :-\

[PhilD73]

Is my entry (the water being splashed up by the car) OK then? I had thought that was kinetic energy in motion...

Cheers,
Phil

Actually, kinetic energy is defined as follows:

The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed.

It is the energy of motion.

[dvdowns]

I know this isn't a science forum but any form of motion is really kinetic energy as with the statement that the brakes of your car work by converting kinetic energy into heat energy , any form of motion is due to kinetic energy . Something hitting something else is merely a transfer of kinetic energy from one object to another .

Hope I'm not too late. Took this one through the plexiglas at my son's firsst team practice of the year.

I think the entries are fine....


Energy that a body has as a result of its motion. Mathematically, it is defined as one-half the product of a body's mass and the square of its speed.
www.science501.com/PTWeaGlGM.html

Energy of motion; the energy a moving object has because of its motion.
wblrd.sk.ca/~chem30_dev/appendix/glossary.htm

The energy a body has by virtue of its motion. The kinetic energy is the work done by an external force to bring the body from rest to a particular state of motion. See: work.

Energy available as a result of motion that varies directly in proportion to an object's mass and the square of its velocity.

Kinetic Energy = (arrow weight) / 450,800 x (arrow speed). Kinetic energy measures the level of penetration your arrow posesses.

Energy associated with motion.
www.nmlites.org/standards/science/glossary_3.htm

Energy of motion, proportional to the total weight of the vehicle and the square of its speed. Thus if a vehicle's weight doubles its KE also goes up two times; but if its speed doubles its KE increases by two squared, ie four times. See 'Recovery - snatch-towing'

1. The energy of a working fluid caused by its motion. 2. Energy related to the fluid of dynamic pressure, 12 pV2.
www.control.co.kr/dic/dic-k.htm

The form of energy associatedwith the speed of an object. Its equation is: KE=1/2mv2(squared); or kinetic energy= ? mass x velocity squared. (It is obvious from the formula that increasing clubhead velocity has more potential for producing distance than increasing the clubhead weight.)

The energy inherent in a substance because of its motion, expressed as a function of its velocity and mass, or MV 2 /2.

is the energy a substance possesses by virtue of its velocity of motion. It enters into dynamic and ejector compressor calculations, but seldom into positive displacement problems.

Energy contained in moving objects such as a rock rolling down a hill, the wind blowing through the trees, or water flowing over a dam.

is energy of motion. Remember roller coasters? A car that moves faster has more kinetic energy than a car that moves slower. Atoms have "Kinetic Energy" too because they move. The atoms in a hot object move faster than atoms in a cold object. The atoms in a hot object have more kinetic energy than the atoms in a cold object. Adding heat to a substance will make the atoms vibrate more and when heat leaves the substance; the atoms will vibrate less.
www.mansfieldct.org/schools/mms/staff/hand/heatvoc.htm

Kinetic energy is the energy of motion. An object which has motion - whether it be vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). KE = ½ * m * v 2

A thermodynamic property. The energy associated with the mass and velocity of a body.

the mechanical energy that a body has by virtue of its motion
wordnet.princeton.edu/perl/webwn

Kinetic energy (also called vis viva, or living force) is energy possessed by a body by virtue of its motion. The kinetic energy of a body is equal to the amount of work needed to establish its velocity and rotation, starting from rest.

Kevin - that's a brilliant post! I don't know whether to laugh or sign up for another college degree
