Used by AQA, Edexcel and OCR
Specification 4.5.1.2 · Paper 2
The pulling force exerted by a stretched rope, string or cable.
Revise: Contact and non-contact forcesTension is a pull transmitted by a stretched rope, string or cable. A surface can also push on an object touching it; this normal contact force acts at right angles to the surface. For example, a desk pushes upwards on a book resting on it.
Specification 9.4 · Paper 2
Revise: Free Body Force DiagramsLabel it with the type of force, such as weight, normal contact force, friction or tension. Add its value and the unit N when these are known. If the diagram must be drawn to scale, choose and state a suitable scale before drawing.
Specification P2.2h, P2.3a · Paper 1 (Foundation), Paper 3 (Higher)
A pulling force transmitted by a taut rope, string or cable, directed away from the object along the rope, string or cable.
Revise: EquilibriumFor example, a hanging object can have a downward weight and an equally large upward tension.
The pulling force transmitted through an object such as a rope, cable or stretched spring.
