  1. What is tension? (article) | Tension - Tension | Khan Academy

    Unfortunately, there's no special formula to find the force of tension. The strategy employed to find the force of tension is the same as the one we use to find the normal force.

  2. The force of tension (video) | Tension | Khan Academy

    Tension refers to the force that is transmitted through a string, rope, wire, or other similar object when it is pulled tight, trying to restore the object to its original, unstretched length. Learn how …

  3. Introduction to tension (part 2) (video) | Khan Academy

    Learn how to calculate tension in wires using trigonometry, vector components, and algebra. Understand how tension varies in different wires based on their angle and force of gravity.

  4. Circular motion (article) | Khan Academy

    At the top of the circle, F → T gets the maximum possible assistance from F → g in providing the inward radial force necessary to keep the block going around the circle. How much tension …

  5. Introduction to tension (video) - Khan Academy

    Learn how tension, the force within or applied by a string or wire, counteracts gravity to keep objects stationary. Explore how tension varies in different scenarios, like in a system with …

  6. Forces and Newton's laws of motion | Physics archive | Khan …

    Unit 1: Forces and Newton's laws of motion About this unit For our most up-to-date, mastery-enabled courses, check out High School Physics, AP Physics 1, and AP Physics 2!

  7. Work example problems (video) | Khan Academy

    You'll also understand the formula definition of work and how forces like tension, friction, and gravity play a role, and be able to apply the work-energy principle to determine an object's final …

  8. Centripetal force problem solving (video) | Khan Academy

    The only force in this case that points toward the center of the circle is the tension force, and like we already said, that is the centripetal force. So over here, I'd have v squared over r, and that …

  9. Tension examples (video) - Khan Academy

    Learn how to determine the tension force acting on suspended objects in different scenarios.

  10. Tension examples (video) | Tension | Khan Academy

    Learn how to determine the tension force acting on suspended objects in different scenarios.
