Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

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 ...

Abstract: Qualitative motion reasoning is an important approach to spatial commonsense reasoning. In this paper, we propose a qualitative motion reasoning method based on Voronoi diagrams. The method ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

To calculate the Minkowski sum, we move the robot to the point with coordinates (0,0), invert it and then add the coordinates of all obstacles’ corners with each point of the robot. Of course, we have ...

Abstract: The sampling-based partial motion planning algorithm has been widely applied in real-time mobile robot navigation for its computational savings and its flexibility in avoiding obstacles.

Gravity provides the force needed to maintain stable orbit of planets around a star and also of moons and artificial satellites around a planet. For an object to remain in a steady, circular orbit it ...
