Study the tiny molecular motors that cells use to produce force and motion in human cells. To break symmetry, all cells polarize making one part of the cell structurally, functionally, or ...

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: ...

Chapter 6 of physics dives into force and motion! Learn how forces impact motion, and explore how acceleration, friction, and Newton's laws work in real-world situations. #PhysicsExplained #ForceAndMo ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...
