What is the force of gravity acting on the block (the weight) in water?
The force of gravity on a block is the same, whether it is in air or in the water. The apparent weight (the force you need to keep it from falling) is less in water, due to the buoyancy force, which counteracts the weight.
What is the upward force on an object?
Lift is the force that counteracts gravity.
Which force acts against the motion of an airplane as it flies through the air?
weight
What force or forces would be acting upon a falling airplane?
gravity wind resistance weight
What are the forces on a airplane when it is still?
Gravity on the plane itself, the weight of any occupants (force of gravity on occupants), and any force applied by weather influences such as wind.
What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.

What are the four force acting on a airplane?
lift, thrust, drag and weight(gravity)

weight
Why is the force of gravity is not exactly the same everywhere on earths surface?
Two reasons: 1. Different distances from the Earth's center; 2. A "centrifugal force" that counteracts gravity in part.Two reasons: 1. Different distances from the Earth's center; 2.

What force or forces would be acting upon a falling airplane?
gravity wind resistance weight
Even though a brick weighs less in a metal hull ship a brick in the bathtub sinks but a metal hull ship in the ocean floats why?
It floats because the shape of the hull with a large cavity inside displacing the water counteracts the weight of the metal hull. The water displacement counteracts the force of gravity, spreading the weight of the boat out across a larger surface area with a great tensile strength, resisting the force of gravity.
In an airplane the lift force is used to overcome weight in a model rocket is what used to over come weight?
Thrust, strong and powerfull
What are the three forces that act on an airplane?
Lift: The force that keeps the plane flying.Drag: The force that slows down the plane. Weight: Theattractionto the ground.
What force counteracts a planet's inertia and keeps the planet in its orbit?
Gravity counteracts this inertia, usually the gravity of a body much larger than itself.
Is Buoyancy an upward force exerted by a fluid on a body placed in the fluid?
False. It is an upward force, that (partly) counteracts the downward force of gravity for objects within a liquid. It is related to the resistance (to displacement) by the liquid molecules.
