What to enter
| Input | Meaning and units |
|---|---|
| Mass (kg) | Enter mass in kg; use the same basis as the other measurements. |
| Speed (m/s) | Enter speed in m/s; use the same basis as the other measurements. |
Understanding your result
Read Kinetic energy (J) in the units and model stated on this page. The formula energy=m*v*v/2 defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
