Paano Kalkulahin si Rotational K E
Ano ang Rotational K E?
Rotational kinetic energy is the energy of spinning objects. It depends on both moment of inertia and angular velocity, analogous to translational kinetic energy.
Pormula
The calculator applies KE_rot = ½ × I × ω²
- I
- I value — Variable used in the calculation
Step-by-Step na Gabay
- 1Enter the moment of inertia (I) and angular velocity (ω)
- 2The calculator applies KE_rot = ½ × I × ω²
- 3Results show rotational energy in joules
Mga Nalutas na Halimbawa
Input
I = 2 kg·m², ω = 10 rad/s
Resulta
KE_rot = 100 J
Compare to ½mv²
Mga Karaniwang Mali na Dapat Iwasan
- ✕Using linear mass instead of moment of inertia in the formula
- ✕Forgetting to square the angular velocity
Mga madalas itanong
How does moment of inertia relate to mass distribution?
Objects with mass concentrated far from the rotation axis have higher moment of inertia and require more energy to spin.
Can kinetic energy be converted between rotational and translational?
Yes, rolling objects convert between both types; the total kinetic energy is the sum of both components.
