For a moving object, the velocity can be represented by a velocity-time graph. A horizontal line on a velocity-time graph, shows that the object is at constant velocity, but a sloping line on a ...

For a moving object, the distance travelled can be represented by a distance-time graph. A horizontal line on a distance-time graph shows that the object is stationary (not moving), while a sloping ...

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 ...

Mathematicians have finally succeeded in unifying the laws of physics that govern the motions of particles at different scales. Their efforts resolve a question set by mathematician David Hilbert in ...

Perpetual motion—it's fun to say that. For some people, perpetual motion machines hold the secret to everlasting free energy that will save the world. To them, it's a machine that is just beyond our ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...
