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 net force acting on the object can be calculated using the equation F = m*a, where F is the force, m is the mass of the object, and a is the acceleration due to gravity. The mass of the object can be converted from pounds to slugs, and the acceleration due to gravity is approximately 32 ft/s^2. Plugging in the values, we can calculate the net force.

How much weight does a 80 pound object falling 10 feet create?
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.
Why the air resistance decrease the acceleration on falling object?
Air resistance applies a force opposite to the direction of motion of a falling object. This force opposes the force of gravity, reducing the net force acting on the object, and hence reducing its acceleration. As the object's speed increases, the air resistance force also increases, further hindering its acceleration.
How much force are you exerting when you lift a 50 pound dumbbell?
When you lift a 50 pound dumbbell, you are exerting a force equal to the weight of the dumbbell, which is 50 pounds or approximately 222.4 Newtons. This force is required to overcome the gravitational pull on the dumbbell and lift it against gravity.
What is the buoyant force acting on a 1000 pound floating in water?
The buoyant force acting on an object is equal to the weight of the fluid displaced by the object. For a 1000 pound object floating in water, the buoyant force acting on it would be equal to 1000 pounds, which is the weight of the water that it displaces.
Which has more mass 1 pound of water or 1 pound of steel?
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.

What is one pound of tension?
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.
How much force are you exerting when you lift a 50 pound dumbbell?
When you lift a 50 pound dumbbell, you are exerting a force equal to the weight of the dumbbell, which is 50 pounds or approximately 222.4 Newtons. This force is required to overcome the gravitational pull on the dumbbell and lift it against gravity.
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.
What is the buoyant force acting on a 1000 pound floating in water?
The buoyant force acting on an object is equal to the weight of the fluid displaced by the object. For a 1000 pound object floating in water, the buoyant force acting on it would be equal to 1000 pounds, which is the weight of the water that it displaces.
How many pound of pressure does a 80 pound person make when falling?
it depends how far they are falling
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.
Which has more mass 1 pound of water or 1 pound of steel?
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.
What is the velocity of a 4.5 Pound object falling thirty feet?
The velocity of a 4.5 pound object falling from a height of thirty feet can be calculated using the equation for free-fall motion: ( v = \sqrt{2gh} ), where ( v ) is the velocity, ( g ) is the acceleration due to gravity (32 ft/s(^2)), and ( h ) is the height. Substituting the values, you can calculate the velocity of the object when it reaches the ground after falling thirty feet.
