Find the force of gravity acting on a body weighing 1.5 tons.

Problem data: m (mass of a given body) = 1.5 t (in SI m = 1.5 * 10 ^ 3 kg).

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

The sought gravity acting on a given body is equal to its weight and corresponds to the product of a constant value of the acceleration of gravity and the indicated mass: Ft = P = m * g.

Let’s make a calculation: Ft = 1.5 * 10 ^ 3 * 10 = 15 * 10 ^ 3 = 15 kN.

Answer: The force of gravity is 15 kN.
