Customized Adjustable Long Extension Springs Helical Stainless Steel 0.05-20.0mm

1. What is the key difference between tension and spring force?
The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire. The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it.

2. What is the tension of a string?
In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements.

3. Is tension equal to weight?
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.

4. Why is tension important in physics?
If one of the force exerting object is a rope, cable or chain, you can call it as tension. Cables and Ropes can be used for exerting forces since they can transfer a force over a specific distance efficiently (e.g. the rope length). Please note that tension is the pulling force since ropes cannot push effectively.

5. Can tension be a normal force?
Tension is just a pulling force that a rope gives to the object it is attached to. It has nothing to do with normal force. the force with which the block pulls the force back can be called normal which even though will have magnitude of tension as per newtons third law they are different.
