1) Body weighing 3.5 kg.
Fт = m * g, where m is the mass (m = 3.5 kg), g is the acceleration of gravity (we take g = 10 m / s²).
Ft = m * g = 3.5 * 10 = 35 N.
2) A body weighing 400 g.
Ft = m * g, where m is the mass (m = 400 g = 0.4 kg).
Ft = m * g = 0.4 * 10 = 4 N.
3) A body weighing 1.5 tons.
Ft = m * g, where m is the mass (m = 1.5 t = 1500 kg).
Ft = m * g = 1500 * 10 = 15000 N.
4) A body weighing 60 g.
Ft = m * g, where m is the mass (m = 60 g = 0.06 kg).
Ft = m * g = 0.06 * 10 = 0.6 N.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
