Question

A 28 kg student stand on the surface of the Earth. What is the magnitude of the

gravitational force of the earth on the student?

Answer 1

F = 274.68[N]

Step-by-step explanation:

The gravitational force is equal to the weight of a body, or this case that of a person. Weight can be calculated by means of the product of mass by gravitational acceleration. In this way we have the following equation:

`F=m*g`

where:

F = force or weight [N]

m = mass = 28 [kg]

g = gravity acceleration = 9.81 [m/s²]

Now replacing:

`F=28*9.81\\F=274.68[N]`
