How will the kinetic energy of a body change if its speed is halved?
| December 21, 2020 | education
To solve this task, we first of all need to know that kinetic energy depends on mass and speed, E = m * (speed squared) / 2, so if we reduce the speed by 2 times, then the denominator will be 4, that is, energy will decrease by 4 times.
