What else can I help you with?
How does the direction of the lift on a plane compare with its weight as it flies at a constant speed and altitude?
The lift force on a plane is equal to its weight when it is flying at a constant speed and altitude. This balance is necessary for the plane to maintain level flight. If the lift force becomes greater than the weight, the plane will climb; if the lift force becomes less than the weight, the plane will descend.
What happens if the thrust of a plane becomes greater than the drag?
If the thrust of a plane becomes greater than the drag, the aircraft will accelerate forward. This increase in speed can lead to the plane climbing if the lift generated by the wings also exceeds the weight of the aircraft. However, if the thrust continues to significantly exceed drag, the plane will gain altitude and speed until it reaches a new equilibrium or until other factors (like engine limits or air density) come into play.
What happens if the Weight greater than lift on a plane?
If the weight of the plane is greater than the lift produced by its wings, the plane will not be able to maintain level flight and will start to descend. This situation is known as a stall, and if not corrected promptly, it can lead to a loss of control and potential crash. Pilots use various techniques to avoid stalling, such as adjusting the angle of attack or reducing the weight of the aircraft.
What happens if thrust is greater than drag?
The car (or plane/whatever else it is) accelerates. This means that it gains speed
Dose lift have to be greater than weight for a plane to land?
Yes, in order for a plane to land safely, the lift (created by the wings) must be greater than the weight of the aircraft. This helps the plane maintain control during the descent and landing process.
How much effort is needed if the length of the inclined plane is shorter?
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.
What happens to the mechanical advantage as the inclined plane gets steeper?
As the inclined plane gets steeper, the mechanical advantage decreases. This is because the force required to overcome gravity becomes greater as the angle of incline increases, requiring more effort to move an object up the ramp.
How does the angle of an incline plane affect the force needed to move and object?
The steeper the incline plane, the greater the force required to move an object up the incline. This is because the component of the force needed to overcome gravity acting against the object's weight on the incline becomes larger as the angle increases. A shallower incline requires less force to move the object up it.
If you were on a mountain would the weight of the air above be greater than or less than it is at sea level?
That would depend where you are. The weight of air above you is greater at sea level than up a mountain, but if you were in a plane it might well be less than up a mountain.
How does an airplane take off?
During takeoff, an airplane's engines produce thrust, pushing the aircraft forward. As the speed increases, air flows over the wings, creating lift. When there is enough lift to overcome the aircraft's weight, it becomes airborne. The pilot then guides the plane into the sky.
What is the effect of the angle of inclination of inclined plane on the effort exerted?
The greater the angle of inclination of an inclined plane, the greater the effort required to overcome gravity and move an object up the incline. This is because the component of the weight acting against the direction of motion increases as the angle of inclination increases.
What are the disadvantages of an inclined plane?
The disadvantage of an inclined plane is you need a greater force.
