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 ...

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 ...

I am thinking about adding another rule to my Perpetual Motion Guidelines. Currently, I only read crazy idea emails if they meet the following: I am considering adding this: If the perpetual motion ...

Two forces can be added together to find a resultant force. In the diagram of a toy trailer below, when two children pull on the handle, one with a force of 3 newtons (N) to the left and one with 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 ...

You’re probably familiar with the old joke about a physicist who, when asked to use science to help a dairy farmer, begins by approximating a spherical cow in a vacuum. But maybe it’s time to ...

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.
