If it is allowed to fall under the influence of gravity only (ignore air resistance), how fast (in meters per second) is it moving just before hitting the ground? What force affects vertical velocity in biomechanics? What is velocity? Explain. How could you increase the IMA of an incline...
If you fall from a plane without a parachute, your relatively compact body zooms through the air like a stone; open your parachute and you create more air resistance, drifting to the ground more slowly and safely—much more like a feather. Simply speaking, then, a parachute works by ...
The Question : What effect does shape have in air resistance ? well is the surface area is larger the more resistance there is to the air and if the surface area is smaller it allows the air to pass by more easily Wiki User ∙14yago ...
It cools down the incoming air and a dehumidifier removes any excess moisture. The air then flows over a heating element (similar to the one in a fan heater). On a cold day, this part of the unit may be turned right up so the HVAC works as a heater. A fan at the top blasts ...
Second, trying to explain an aerospike engine on a page aimed at the general public in its full physical glory would be fruitless for all but those with a background in compressible gas dynamics. As such, those landing pages are certainly watered down a bit and describe the engines in...
The definition of lift is the force perpendicular to the direction of travel, with respect to the air. Traz 0 said: Bernoulli model The problem with Bernoulli model is that it doesn't explain why the pressure and speed differentials form above and below a wing. Explaing how lift ...
Statistics aren’t the only way to add details to a client testimonial. In fact, sometimes, you’ll be in situations where specific figures or numbers can’t be shared. In those instances, explain the details of the problem, concerns that existed beforehand, or share pertinent background info...

Indoor air pollution from sources like this can irritate your lungs and contribute to allergies and asthma. The trouble is, if you use an ordinary vacuum cleaner, you might simply be "rearranging the dirt": your cleaner will trap some of the dust inside the bag or cyclone filter but let ...
A jet engine uses the same scientific principle as a car engine: it burns fuel with air (in a chemical reaction called combustion) to release energy that powers a plane, vehicle, or other machine. But instead of using cylinders that go through four steps in turn, it uses a long metal ...
