Time is a unit of measurement, just like inches or centimeters or degrees. Time measures distance - like how far away is something, how long will it take to get there? How can anyone justify that time is the forth dimension. It just doesn't make sense. Hasn't anyone ever heard of light-speed? Like how long does light take to reach an object, as a unit of measurement.

Does anyone have any valid arguments? Or can anyone tell me something else that may be regarded as being fourth dimensional? Personally I think you're all retards if you believe that time is the fourth dimension. We are in this 3 dimensional world, and that is all we have to deal with - get over it.

I read that if you can see a dull, cherry-red aura around a Rado Shack sign, it means you are one of the rare people who can see near-infrared. I can do this, but only when it's nighttime. Am I seeing near-infrared? And if I can see a similar aura from around a UV bulb, am I seeing near-UV?

If it is, how rare is that? And is infrared too low-frequency for people to see; or is it like UV, and too high?

two balls with the same mass, one of wood and the other a ping-pong ball partly filled with sand, are rolled along a desk. The wooden ball rolls along nicely, but the ping-pong ball stops in a few centimetres. What happened to its kinetic energy..? well was the kinetic energy changed to heat energy by the force of friction between the ball and the desk..?

Why......why WORK DONE BY THE FORCE a scaler quantity ?

It should be vector....
coz w=f*s
i.e. w= vector*scaler
or., w=vector.
but it is a scaler ? why so ????????????

Think about it, its mostly philosophy based on counter-intuitive thinking that the natural world is made of "strings" which we can't see and are not made of physical atoms but of "supernatural" higher elements. woooow

A 53.0 g ice cube can slide without friction up and down a 35.0 degree slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 12.0 cm. The spring constant is 23.0 N/m.

p.s. it is frictionless

Comment Critically on the following claims:

(a) an object allways accelerates in the direction of the net force
(b)A lower net force is needed to accelerate an object from rest to 10m/s than is required to accelerate it from rest to 20m/s irrespective of the time take.


Best answer gets 10 Points!!!
