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.

Drag (physics) For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow.

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 ...

Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size ...

While small-tire drag racing will never have the overt impact on life that the development and implementation of the steam engine did, both the steam engine and the performance of full-bodied cars ...
