Determine the force of gravity acting on a body weighing 300 g, 5 kg, 5 tons.

m1 = 300 g = 0.3 kg.

m2 = 5 kg.

m3 = 5 t = 5000 kg.

g = 10 m / s2.

Fт1 -?

Ft2 -?

Ft3 -?

The force of gravity Fт is the force with which the earth, as a result of gravitational interaction, attracts all objects located on it.

Ft = G * mt * Mz / Rz2, G – gravitational constant, mt – body mass, Mz – earth mass, Rz – earth radius.

The value G * Mz / Rz2 is called the gravitational acceleration g, the value of which is g = 10 m / s2.

The force of gravity will be determined by the formula: Ft = g * mt.

Ft1 = 10 m / s2 * 0.3 kg = 3 N.

Ft2 = 10 m / s2 * 5 kg = 50 N.

Ft3 = 10 m / s2 * 5000 kg = 50,000 N.

Answer: Ft1 = 3 N, Ft2 = 50 N, Ft3 = 50,000 N.
