Tension force is a force that is exerted equally on both ends of a cable, chain, rope, wire or other continuous object and is transmitted between the ends by that object. On a microscopic level, objects under tension have a separation between molecules that creates potential energy in their bonds.Continue Reading
It requires force to put an object under tension, but technically, tension itself is not a force for as long as the situation is stable. Nonetheless, physicists measure the tension in a system in units of force. Once some part of the system begins moving, such as when one end of a rope under tension is released, the potential energy between the molecules of the rope is converted to mechanical energy, and the tension is converted to force. As long as an object under tension is straight, the tension is constant for its entire length.
A force is any push or pull acting upon an object as a result of its interaction with another object. Tension forces are one of the contact forces, which are the forces present when two objects are in contact with one another. There are also non-contact forces, such as gravity, magnetic force and electrical force, which act at a distance.Learn more about Motion & Mechanics
A truss consists of a set of members that act in compression or tension as a unit, and truss bridges stay up because of the forces that pull outward on the ends of the tension member, forming a triangular structure that keeps the bridge in place. A triangle is the ideal shape to hold this tension because a triangle does not experience distortion from the pushing and pulling of stress.Full Answer >
Friction is a force that opposes motion, so it is unhelpful in all situations where the motion of an object is desired. A by-product of friction is that energy is wasted in the form of heat, which can cause problems in temperature-sensitive environments.Full Answer >
Physics teaches that a contact force is a force acting between two objects, or an object and a surface that are in contact with one another. Gravity and magnetic attraction are examples of non-contact forces, as they work over a distance. Non-contact forces still apply, even when there is a vacuum between the two objects.Full Answer >
Inertia is the tendency for an object to remain in motion or at rest unless it is acted upon by an outside force. In the field of physics, this concept is referred to as Newton's first law of motion.Full Answer >
