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: ...

Students will apply their knowledge of physical science concepts to create a lunar lander game using Scratch. They will use Vernier force and acceleration sensors to understand forces and integrate ...

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 ...
