A 31.5 N object is in free fall.

What is the magnitude of the net force
which acts on the object?
Answer in units of N

31.5

31.5 N because its in free fall the only force on it is gravity so Fg=mg and Fg is given in the question.

31.5

To determine the magnitude of the net force acting on the object, we need to understand the concept of free fall. In free fall, a body is only subject to the force of gravity. The net force acting on the object will be equal to the force of gravity.

The force of gravity acting on an object can be calculated using Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration.

Since the object is in free fall, its acceleration is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 on Earth.

Therefore, we can calculate the force of gravity using the equation:

Force of gravity = mass × acceleration due to gravity

In this case, we are given the weight of the object as 31.5 N. The weight of an object is the force of gravity acting on it, and it is equal to the mass of the object multiplied by the acceleration due to gravity.

Hence, to find the mass of the object, we need to rearrange the equation:

mass = weight / acceleration due to gravity

Let's plug in the values:

mass = 31.5 N / 9.8 m/s^2

By dividing 31.5 N by 9.8 m/s^2, we can calculate the mass of the object. Once we have the mass, we can determine the magnitude of the net force acting on the object, which will also be equal to the weight of the object.

Hence, the magnitude of the net force acting on the object is 31.5 N.
