Determine the force of gravity acting on a body weighing 3.5kg; 400g; 1.5t; 60g. Find the body weight that weighs 5kg; 300g. Human weight 700N. Determine its mass. Express the following forces in newtons: 240kN, 25kN, 5kN, 0.2kN. There is a 5kg TV on the table. Determine the gravity and weight of the TV.

m1 = 3.5 kg.

m2 = 400 g = 0.4 kg.

m3 = 1.5 t = 1500 kg.

m4 = 60 t = 60,000 kg g = 10 m / s2.

m5 = 5 kg.

m6 = 300 g = 0.3 kg.

mbody = 5 kg.

P7 = 700 N.

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

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

Fт1 = 10 m / s2 * 3.5 kg = 35 N.

Ft2 = 10 m / s2 * 0.4 kg = 4 N.

Ft3 = 10 m / s2 * 1500 kg = 15000 N.

Fт4 = 10 m / s2 * 60,000 kg = 60,000,000 N.

The weight of the body P is the force with which the body presses on the support or stretches the suspension.

P = g * mt.

P5 = 10 m / s2 * 5 kg = 50 N.

P6 = 10 m / s2 * 0.3 kg = 3 N.

m7 = P7 / g.

m7 = 700 N / 10 m / s2 = 70 kg.

F = 240 kN = 240,000 N.

F = 25 kN = 25000 N.

F = 5 kN = 5000 N.

F = 0.2 kN = 200 N.

Ftel = Rtel = g * mtel.

Ftel = Ptel = 10 m / s2 * 5 kg = 50 N.
