The net force on a 7 pound object that is falling (accelerating down) is 7 pounds. If it is not falling or moving at a constant speed, it is zero.

How much force are you exerting when you lift a 50 pound dumbbell?
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
How much force would be needed to lift a 200-pound object with a double pulley?
25 newtons
What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
How many inch pounds of torque are equal to 9 newton pounds?
You could have 'newton-centimeters', or 'newton-inches', or 'pound meters' etc., but you can't have 'newton pounds'. Torque is (a distance) x (a force), but 'newton pound' is (force) x (force). Whether or not that has any physical significance at all, it's surely not torque.
What is the buoyant force acting on a 1000 pound floating in water?
If it's floating, then the buoyant force on it is exactly equal to its weight. (That makes the vector sum of the vertical forces zero, which is why the object is not accelerating vertically.)
How much force are you exerting when you lift a 50 pound dumbbell?
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
What is one pound of tension?
A one pound force applied in a pulling fashion on an object.
If a resistive force torque is 200 pound-inches and fa equals 4 inches what F equal in the following equation 200 pound-inches equals F x4 inches?
the answer is 50 pounds.
A 90 pound object going 30 miles per hour has how much force?
no force, it has momentum
What unit of force is used to measure the weight of an object?
Any unit of force that appeals to you.The "pound-force" (usually called simply the "pound") and the "newton" are the most popular. Note: The "gram" and the "kilogram" are NOT units of force.
How many pound of pressure does a 80 pound person make when falling?
it depends how far they are falling
How much force would be needed to lift a 200-pound object with a double pulley?
25 newtons
How many millilters of water make 1 pound of weight?
The question cannot be answered sensibly because a pound is a measure of mass which is not the same as weight. The weight of an object depends on the force of gravity acting o it and that force depends on the position of the object and other masses near it.
What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
What is the resultant force in each if A 100 pound force to the west and a 50 pound force in the same direction?
A 150 pound resultant force
What do you call the measurement of the gravitational force acting on an object?
Basically it is the object's "weight". The gravitational force on an object is its Mass X Gravitational Constant. The gravitational constant is the acceleration of a free falling body towards another body, and on Earth is equal to 9.81 meters/sec2 or 32.2 feet/sec2. Thus while the MASS of an object is a constant physical property, the WEIGHT of an object depends on the local gravity field pulling on that MASS.
How many foot-pounds of work must be expended to lift a 1500 pound object 60 inches?
(1,500 pounds) x (60 inches) / (12 inches per foot) = 7,500 foot-pounds
