Explore work and energy concepts with a real-world example: a crashing car analysis! In this physics tutorial, we break down kinetic energy, work done, and energy transfer during a collision. Using ...

Energy plays a tremendous role, not only in our technology-rich daily lives, but in fundamental physics as well. The chemical energy stored in gasoline gets converted into kinetic energy that propels ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
