2.2 Speed and Velocity - Physics | OpenStax

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "This experiment demonstrates the speed of light — one of the fastest things in the universe! 🌌 Even in a simple room setup, physics can show how light zips through space at 299,792,458 meters per second. 🔬💡 It’s a perfect example of how mind-blowing science can be shown with everyday tools. 🚀 📩 DM for credit/removal ✅ Follow @ofc_exp_science007 #SpeedOfLight #PhysicsExperiment #ScienceExplained #MindBlowingScience #ExploreScience #STEMDa

Physics Experiment on Instagram: "Inertia (Newton’s First Law) means an object keeps moving at the same speed and direction unless a force acts on it. So, here, the ball initially wants to keep moving forward with the car’s speed. But then, the ball is thrown backward at the same speed as the car’s forward motion so the speeds cancel out (relative to the ground). 🚗 40km/h - ⚽️ 40km/h = 🛑 0 km/h Now, this canceling of speeds happens because you give the ball a backward velocity equal to the car
