Learn how to analyze motion graphs in physics, including position-time and velocity-time graphs. This video explains slopes, areas, and motion behavior to help you clearly interpret real physics ...

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 ...

In this video, we solve a classic AP Physics 1 ramp to projectile motion problem step by step, showing how energy, kinematics, and motion concepts connect. Ideal for exam prep and for students looking ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along ...

How do skateboarders seemingly defy gravity? How do gymnasts flip in the air? They have skill — and, as a Times interactive explored, an understanding of the laws of motion, physics and energy. By ...
