In the world of physics, force is the strength or energy needed to create movement. Drag opposes motion as it moves through the air or water.

All the latest science news on drag force from Phys.org. Find the latest news, advancements, and breakthroughs.

The team found that the superhydrophobic sphere experienced about 50% more drag just as the spheres were being fully submerged. Harris explains this using simple physics. “Essentially, the water that ...

This method capitalizes on the force balance that exists when a falling object reaches terminal velocity. At terminal velocity, all of the forces sum to zero, and therefore the drag may be estimated ...

“We hypothesized that on a shark, these denticles may also be beneficial for thrust generation by enhancing the force normal to the denticle,” Domel told Physics World. “With this in mind, we wanted ...

Instead, the tiny insects rely on a drag-based flight mechanism, keeping themselves afloat in airflow velocities with a large ratio of force to wing size.

The force the air exerts on the ball is ultimately due to collisions with the air particles and the ball. If the ball is spinning and non-smooth, there can be complex interactions.

Farah is still an undergraduate, studying physics and math at the University of Massachusetts-Boston. He is the first and only undergraduate thus far to receive junior collaborator status on the ...
