What occurs if the air moves faster above an object than below it?
Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.
An object propelled into the air but has no power to keep itself in the air?
The object will fall back to the ground due to gravity acting on it. Without a source of lift or propulsion to counteract gravity, the object cannot stay in the air.
What happens if the lift become greater than gravity?
If the lift force becomes greater than gravity, the object will experience an upward acceleration. This could result in the object lifting off the ground or moving upwards, depending on various factors such as air resistance, weight, and drag. If the lift force continues to be greater than gravity, the object will continue to accelerate upwards.
Why it is easy to lift an object inside the water?
It is easier to lift an object inside water because water exerts an upward buoyant force on the object which counteracts the force of gravity pulling the object downwards. This makes the object feel lighter and easier to lift compared to in air.
What causes lift?
lift is when air is blown at a moving object and the shape of the object pushes it down and itself up as an example when a plane moves down the runway, the air is pushed down by the shape of the wings
What is the force that opposes lift?
The force that opposes lift is drag. Drag is the aerodynamic force that acts opposite to the direction of motion of an object moving through a fluid (such as air). It is caused by air resistance and friction as the object moves through the air.
What is created when air currents dont meet up the right way after passing by an object?
What is created when air currents dont meet up the right way after passing an object? a) lift b) slope c) drag d) hydraulics A) LIFT is the answer
Will heat move from the ground to the atmosphere by conduction if the air is warmer than the ground?
No, heat will not move from the ground to the atmosphere by conduction if the air is warmer than the ground. Conduction involves heat transfer from a warmer object to a cooler object, so in this case, heat will not flow from the ground to the already warmer air.
What has to happen in order to make something fly?
In order to make something fly, it needs to generate enough lift force to counteract the force of gravity pulling it down. This is typically achieved through the use of wings or other aerodynamic surfaces that create lift as the object moves through the air. Additionally, the object must overcome drag, which is the resistance of the air to its motion.
How can air resistance help the motion of an object?
Normally, air resistance slows an object and this does not help motion, it impedes it. Lift, which is an aerodynamic force, is very helpful and it's caused by air resistance. This allows a plane to lift off and stay in flight.
Is there a real hovercraft?
Yes, they use high pressure air flow to lift the vehicles of the ground on a cusion of air.
How much air pressure to lift a 1 kilo of object?
i will hurt is all i can say
