Does drag slow a moving object?
Yes.
What is air resistance and how does it affect a falling object?
Air resistance is the force acting on an object moving in air that tends to slow it down or produce drag. If a stone is falling, air resistance will be acting on it to try to slow it. Should we consider a jet moving through air, air resistance will be providing drag to slow the jet down.
Why does drag slow you down in swimming?
When you are not in a streamline position in swimming, drag can occur. This is when you body is stopping the water from freely moving past your body. You may notice when you begin to sink while you are swimming that you slow down. This is because the lower part of your body is creating drag by stopping the water from quickly passing you legs.
How does an airplane slow down?
* An airplane with jets slow down by flaps that fold in to reverse the airpane(go on youtube.com and write" how a jet engine slows down" for more information) * An airplane with propellers just spins the other way!
What are the slats on an airplane wing?
to slow it down quicker
Why would a ball would never stop moving if you give it a push (apply a force to it) in outer space?
There is no force of drag or friction acting to slow it down.
What waste more gas windows down or air conditioner?
windows down- more drag. It would take more gas to keep the car moving because the windows would slow the car down.
What are forces that cause a CO2 dragster to slow down?
drag
What are the flaps on an airplane used for?
The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.
Do planes have gravity when in the air?
Yes, gravity affects everything that has mass, everywhere, all the time. In the case of an airplane, gravity is pulling the airplane down. The engines move the airplane forward, and the speed of the air over the wings causes lift, which pulls the aircraft UP. The friction or "drag" of the aircraft moving through the air causes the plane to slow down. It's a delicate balance; the thrust of the engines, and the drag of the airflow, and the airflow causing lift which counteracts gravity. But you can do one simple experiment which proves that gravity affects the plane and everything in it. When you are in an airplane in flight, take your inflight magazine and hold it about 10 inches above your lap; then let go. Gravity affects the magazine and pulls it down.
What is slow moving river of ice definition?
A "slow moving river of ice" is a glacier. A slow moving chunk of ice floating down a river is a "floe".
What term describes the air resistance that slow down aircraft?
Drag
