What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
What is the role of lift in flight?
"Lift" is the force that acts opposite to gravity. If 'lift' can be made to exceed the weight of the craft, then the net vertical force on it is directed upward, and the craft can rise.
How does the direction of the lift on a plane compare with its weight as it flies at a constant speed and altitude?
lift acts upward, and weight acts downward
What does lift do to the airplane?
Lift acts against the force of gravity, pushing the aircraft up.
What force pulls an aircraft toward the ground acts against the force of lift in level flight?
Gravity

When you lift a box off the ground gravity opposes your lifting force true or false?
Well, it's true that the gravitational force acting on the box acts in the direction opposite to the direction of your lifting force, but there's nothing malicious or contrary about it. In fact, the gravitational force was there before you came on the scene, and as you lined up your lift, it was you who decided to oppose it.

A rocket receives lift off due to?
A rocket is able to lift off because of something called thrust. This means if you apply force to one direction, it will also apply force to the opposite direction.
What is drag for an airplane?
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
What is the opposite of lift?
The opposite of the verb to lift is to lower.The opposite force factor, opposing aerodynamic lift, is weight. (gravity)
Is thrust the upward force the opposes the force of gravity?
Actually thrust is aerodynamically involved, its the driving force that accelerates the aircrafts in forward direction and the opposite force is drag. The opposing force against gravity in a flight is lift.
How does the direction of the lift on a plane compare with its weight as it flies at a constant speed and altitude?
lift acts upward, and weight acts downward

What is force of lift and thrust?
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
What does lift do to the airplane?
Lift acts against the force of gravity, pushing the aircraft up.
A fixed single pulley that is used to lift a block does what?
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required
