What makes something fly?
An object can fly when the forces of lift and thrust are greater than the forces of weight and drag. Lift is generated by the shape of the object (such as wings on an airplane) and thrust is the force that propels the object forward.
Is thrust a motion that will speed up an object?
Thrust is a force that propels an object forward or upward by expelling gas or fluid in the opposite direction. It can increase the speed of an object if the net force of thrust is greater than the opposing forces like drag or gravity acting on the object.
When an object is speeding up through the air are the forces of thrust and drag balanced?
No. This is because the object is speeding up, therefore more force must be acting on one side than on the other. However, if the object was moving at a constant speed or was stationary, then the forces would be balanced.
What force must be created by an airplane in order to overcome drag?
The thrust force produced by the airplane's engines must be greater than the drag force acting against it in order to overcome drag and maintain forward motion. This allows the airplane to continue moving through the air and generate lift to stay aloft.
What causes a force to produce motion?
To move an object forward from rest the thrust of forward force must be greater than the drag acting in the opposite direction. In order to keep moving at a constant velocity the forward force must equal the drag.
What happens if thrust is greater than drag?
The car (or plane/whatever else it is) accelerates. This means that it gains speed
Is thrust greater than drag?
yes
When is thrust greater than drag?
The object accelerates.
What happens to the four forces in order to make an airplane fly?
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.
What happens if the Thrust is greater than drag on an airplane?
If thrust is greater than drag on an airplane, the aircraft will accelerate forward. This surplus thrust allows the plane to gain speed, which is essential for takeoff and climbing. As the speed increases, the lift generated by the wings also increases, enabling the aircraft to ascend. In essence, a net positive thrust leads to improved performance and maneuverability.
What happens if thrust greater than drag in airplane?
When thrust is greater than drag in an airplane, the aircraft accelerates forward. This occurs during takeoff or when the pilot increases engine power. As the speed increases, the airplane generates more lift until it reaches the necessary speed for flight. Ultimately, the surplus thrust allows the aircraft to climb or maintain a higher speed.
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 when a flying airplane has less thrust than drag?
It will stall and begin to lose altitude.
What would happen if the thrust becomes greater than the drag?
If the thrust becomes greater than the drag, the object will accelerate in the direction of the thrust. This imbalance means that the net force acting on the object is positive, leading to an increase in speed. In the context of an aircraft, this could result in climbing or gaining altitude. Conversely, in a projectile, it could enhance its velocity until other factors, such as gravity or fuel depletion, come into play.
How come an airplane floats in air?
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.
When a rocket launches what must the thrust of the engines be greater than?
When a rocket launches, the thrust of its engines must be greater than the gravitational force acting on the rocket, which is the weight of the rocket. This ensures that the rocket can overcome Earth's gravity and lift off the ground. Additionally, the thrust must also be sufficient to counteract any atmospheric drag during ascent.
What makes something fly?
An object can fly when the forces of lift and thrust are greater than the forces of weight and drag. Lift is generated by the shape of the object (such as wings on an airplane) and thrust is the force that propels the object forward.
