What is the mass of a body on which a gravity force of 25 kN acts at the surface of the earth?

The force of gravity (body weight) that acts on the body can be calculated using the formula:

Ft = m * g, where Ft is the force of gravity acting on the body (Ft = 25 N = 25 * 10³ N), m is the mass of the body (kg), g is the acceleration of gravity (we take g = 10 m / s²).

Let’s express and calculate the body weight:

m = Ft / g = 25 * 10³ / 10 = 2500 kg = 2.5 t.

Answer: Body weight is 2.5 tons.
