Kinetic Energy Formula
也称为: KE Formula
KE = \frac{1}{2}mv^2
KE = ½mv²它计算什么
The energy an object possesses due to its motion. Doubling the speed quadruples the kinetic energy.
变量
| 象征 | 姓名 | 描述 |
|---|---|---|
| KE | Kinetic Energy | Energy of motion |
| m | Mass | Mass of the moving object |
| v | Velocity | Speed of the object |
工作示例
1
KE = ½ × 1500 × 20²2
KE = 750 × 400 = 300,000 J = 300 kJ结果: 300 kJ
常见错误
Energy scales with v², so small speed increases have big energy impacts
Use consistent SI units (kg, m/s)
