A raft is floating along the river. Are the kinetic energies of 1 m3 of water and 1 m3 of wood the same? Why?

1 m³ of most types of wood has a mass of less than 1 ton, 1 m³ of fresh water has a mass of 1 ton. Since the kinetic energy (energy of the body’s motion) is directly proportional to the mass of the moving body, it will be greater for the body that has a large mass. Consequently, the kinetic energy of 1 m³ of wood is less than the kinetic energy of 1 m³ of water, given the same speed of movement.

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.
