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.
The force a falling object exerts upon impact is dependent on the object's mass, gravity, and the distance fallen. Using the formula F = mgh, where F is the force, m is the mass, g is the acceleration due to gravity, and h is the height fallen, the force exerted by an 80-pound object falling 10 feet would be approximately 3520 pounds.
Drop a pound of feathers (in a bag) and a pound of lead from a height. The smaller mass of the lead will let it fall faster due to less air resistance, than the greater mass and much greater air resistance of the feathers.
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.
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.)
Both 1 pound of water and 1 pound of steel have the same mass, since they both weigh 1 pound. This is because weight is a measure of the force of gravity acting on an object, while mass is the amount of matter in an object.

One pound of tension is the force exerted by a weight equivalent to one pound on a string, rope, or any other object. It is commonly used as a unit of measurement in physics and engineering to describe the amount of force needed to stretch or pull an object.
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.
the answer is 50 pounds.
no force, it has momentum
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.
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.)
it depends how far they are falling
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.
Both 1 pound of water and 1 pound of steel have the same mass, since they both weigh 1 pound. This is because weight is a measure of the force of gravity acting on an object, while mass is the amount of matter in an object.
To lift a 200-pound object using a double pulley system, the force needed would need to be equivalent to half the weight of the object. This is because a double pulley system reduces the amount of force required by distributing it evenly between the two strands of the rope. Therefore, the force needed would be 100 pounds.
