Lack of motivation might be due to static friction: A physics perspective on why starting is the hardest part

Imagine pushing a heavy box on the floor. It won't move if you push it just a little. As you increase the force, it suddenly starts moving at a certain point. And once it starts moving, you can keep ...

Physicists explain, and eliminate, unknown force dragging against water droplets on superhydrophobic surfaces

"When observing water-surface interactions, there are typically three forces at play: contact-line friction, viscous losses, and air resistance. However, there is a fourth force that arises from the ...
