an object has its weigh 80 n
Take the sum of the forces on the object on the horizontal plane(x-direction) with the positive direction being to the right. The 80 newtons to the right is +80N and the 80 newtons acting to the left is -80N. Add them up, so 80N - 80N = 0 N. The total force acting on the object is 0.
The mass of an object that weighs 80 newtons would depend on the acceleration due to gravity. Assuming a standard value of 9.8 m/s^2 for gravity on Earth, the mass would be approximately 8.16 kilograms (80 newtons divided by 9.8 m/s^2).
On earth it is 784 newtons or 176 lbs.
Mass measured in kilograms is always the same. True weight however is a force measured in Newtons not kg and this is the effect gravity has on a mass.
Well, darling, an object equal to the weight of 80 grams would be... drumroll... an object that weighs 80 grams! It's as simple as that, honey. Just plop 80 grams of anything on a scale, and voilà, you've got yourself an object that weighs 80 grams.
The weight of an object with a mass of 80 kg on Earth would be approximately 784.8 Newtons. This is calculated using the formula weight = mass x gravitational acceleration, where the gravitational acceleration on Earth is approximately 9.81 m/s^2.
Mass is a measure of substance. Weight is a measure of force. Units of mass include kg (kilogram), lbs (pounds). Units of weight are N (newton). If your mass is 80 kg, your weight is 80 X 9.8 N. 9.8 is the force of gravity on the surface of the earth. The further away from the surface you move, the smaller this value will become. If your mass is 80kg on earth, it will be 80kg regardless of where you are. Your weight will however reduce as you move further away from earth.
To convert grams (g) to Newtons (N), you need to use the formula: 1 Newton (N) = 1,000 grams (g) So, to convert 80 grams to Newtons: 80 grams * (1 Newton / 1,000 grams) = 0.08 Newtons Therefore, 80 grams is equal to 0.08 Newtons.
'Weight' is a measure of how heavy something is on the Earth's surface. On the Earth's surface, weight equals mass. Therefore, if a person has a mass of 80kg is on the Earth's surface, her weight is also 80kg, too.
Weight is a force acting on a smaller mass due to a gravitational interaction with a larger mass. The weight of an 80 kg human on a 5.974*10^24 kg planet with a radius of 6378 km (this is earth) is equal to 784 Newtons (or 176 lbs).

Assuming the object is within the Earth's gravitational field and assuming the gravitational field of the Earth during the object's acceleration is constant at 9.81 N Kg-1. The force that the object should be experiencing is a product of the object's mass an velocity thus the force it should be experiencing is 80 multiplied by 9.81. However, the object has a acceleration of 4. Thus, the resultant force it has now is 80 multiplied by 4. Using algebra, 80*9.81 minus 80*4 ca be simplified to 80(9.81-4) which equals 80 multiplied by 5.81. The magnitude of the fictional force is 80 multiplied by 5.81 which is 464.8 Newtons.
