Answer:
Explanation:
The term used for the sum of the kinetic energy of a body is **translational kinetic energy**. This is the kinetic energy associated with the motion of the body as a whole moving through space. For a rigid body, it is given by the formula:
\[ KE_{\text{trans}} = \frac{1}{2} m v^2 \]
where:
- \( m \) is the mass of the body
- \( v \) is the velocity of the body
If you're referring to the total kinetic energy which includes both translational and rotational components for a rigid body, the term would be **total kinetic energy**. This is the sum of translational kinetic energy and rotational kinetic energy:
\[ KE_{\text{total}} = KE_{\text{trans}} + KE_{\text{rot}} \]
where the rotational kinetic energy is given by:
\[ KE_{\text{rot}} = \frac{1}{2} I \omega^2 \]
with:
- \( I \) being the moment of inertia of the body
- \( \omega \) being the angular velocity of the body.
