If the speed of movement of the body increases 3 times, then the kinetic energy of the body will increase ….. times
| April 22, 2021 | education
Kinetic energy is the energy that the body possesses during movement. Its formula is as follows:
Ek = (m * v ^ 2) / 2
From this we can conclude that it is directly proportional to the mass and the square of the speed. If the speed, as in our case, is increased by three times, then the formula shows:
Ek = (m * 3 ^ 2) / 2 = (m * 9) / 2,
that the kinetic energy will increase 9 times.
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.
