surface tension has same dimension as that of?
Any time an object's velocity changes (the object "accelerates"), that is due to a net force. Here are some examples: * A car speeds up. The force is exerted by the tires, on the road. * A car slows down. The force is exerted by the tires, on the road, or by air resistance. * A car moves in a curve (its velocity changes too, since it changes direction). The force is exerted by the tires, on the road. * A planet moves around the Sun. The velocity changes all the time, since the direction changes. The force is exerted by gravity. * A falling object speeds up. The force is exerted by gravity.
Along the rope. A vector arrow would be applied and point directly inward here in many physics books on mechanics.
tension
Force of tension, exerted from the swing rope, keeps the swing moving in the horizontal back and forth motion. The force of gravity keeps the swing from staying at the far right or far left because it always wants the swing to be pulled to Earth, but the force of tension wants to keep it up. Air resistance, like friction, eventually slows the swing down to a halt.
The string n the yo yo r even in newtons I think -Cisco
Force = mass X gravity therefore, 10 X 9.8 = 98 N ==================== -- Assuming that this is all happening near the earth, the 10 kg mass weighs 98 newtons. That means the force of gravity on it is 98 newtons, pointing straight down. -- Since it's just hanging there motionless and not accelerating either up or down, the net vertical force on it must be zero. -- The only other force on it besides gravity is the tension in the rope. -- In order for all the vertical forces on it to add up to zero, the tension in the rope must be exactly equal and opposite to the force of gravity ... 98 newtons pointing straight up.
If the rope is hanging vertical ... one end from the ceiling and the other end to the bucket ... then the tension in the rope is 41.16 newtons (9.26 pounds).
Assuming that all strands are vertical/ parallel to gravity and equally spaced (on a radius) around the centre of gravity then tension on each strand will be equivalent to weight x 9.81 divided by 7 equals tension in Newtons. If the strands are not normal and/or at varying distances from centre of gravity then it becomes a little more complicated. Summ of tension on strands must equal weight of bag. Tension on each strand is a ratio of it's distance from the COG of the furthest most strand. Don't forget the further from perpendicular a strand is the more tension on the strand.

That is known as tension.

Tension
In physics, tension is the magnitude of the pulling force exerted by a string, cable, chain, or similar object on another object. It is the opposite of compression. As tension is a force, it is measured in newtons (or sometimes pounds-force) and is always measured parallel to the string on which it applies.http://en.wikipedia.org/wiki/Tension_(physics)
The force is tension.
