kinetic energy
1
动能, 运动能
the energy possessed by an object due to its motion, defined as one-half the mass of the object multiplied by the square of its velocity, expressed by the equation KE = 0.5 * m * v^2
- When a car is in motion, its kinetic energy depends on both its mass and speed.
当汽车运动时，它的动能取决于它的质量和速度。
