Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

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: ...

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 ...

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 ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...
