Learn how to calculate the tension in a rope pulled by a firefighter using Newton’s Laws of Motion. This video breaks down the forces acting on the rope, explains free-body diagrams, and shows how ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...
