Does constant acceleration really exist in this Universe?
2006-09-07 06:17:03 · update #1
Remember having seen tubular, black spring scales in your Physics lab, called dynamometers?
Well, they are just spring scales...
Suppose you attach three of them to the edge of a flat round table. Then attach the other ends together to a common ring. They will pull out each other until their forces balance and you can read the force each one of them is exerting on the ring. If you change the angle of one of them or you change one of them with another of a different range, you will see that the resting point will change and also all the pulling forces.
Given that the pull of gravity does not affect the balance in this case, it can be concluded that the ring is at rest and all the forces are still present, as you can read on each scale.
Hope that this little experiment will clarify the concept better than any theoretical arguments.

actually it exists when the body is accelerating.
mass interactions can cause bodies to move at constant velocities and in that case forces do not act on the bodies.

force is a push or pull in its most basic form.
and to push or pull we have to have mass.
thr are forces of type gravitional force,electromagnetiv force.
all of them require mass to act.
u can navigate a bit more if u know the concept of weak force and strong force

It's..."ENERGY" does not manifest until mass interactivity occurs at the Atomic level.
