What is the magnitude of the gravitational force acting on an object with a mass of 1 kg?

The options are:
A. 9.81 N
B. 98.1 N
C. 100 N
D. 981 N

Answer :

To determine the magnitude of the gravitational force acting on an object, we can use the formula for weight, which is the force due to gravity. The formula is:

[tex]F = m \cdot g[/tex]

where:

  • [tex]F[/tex] is the force (weight in newtons, N),
  • [tex]m[/tex] is the mass of the object (in kilograms, kg),
  • [tex]g[/tex] is the acceleration due to gravity (approximately 9.81 meters per second squared, [tex]\text{m/s}^2[/tex] on Earth).

Given:

  • [tex]m = 1 \text{ kg}[/tex]
  • [tex]g = 9.81 \text{ m/s}^2[/tex]

We calculate [tex]F[/tex] as follows:

[tex]F = 1 \text{ kg} \times 9.81 \text{ m/s}^2 = 9.81 \text{ N}[/tex]

Therefore, the magnitude of the gravitational force acting on an object with a mass of 1 kg is 9.81 N.

The correct option is: 9.81 N

This problem is classified as a High School Physics question because it involves basic concepts of force and gravity, which are typically covered in high school physics curriculum.
