You can view the rod as having both rotational KE about the center of mass and translational KE of the center of mass. Or you can view the rod as in pure rotation about the given axis. Your choice. Either way, the answer will be the same.ccarit3007 said:
Two points: (1) How did you get that expression for the rotational KE? (2) Realize that ω and v are related. Express everything in terms of ω.ccarit3007 said:
Kinetic energy is the energy an object possesses due to its motion.
The total kinetic energy of a rod can be calculated by multiplying its mass by the square of its velocity, and then dividing by 2:
KE = (1/2) * m * v^2
Kinetic energy is measured in joules (J) in the International System of Units (SI).
Yes, the shape of the rod can affect its kinetic energy. For example, a long thin rod will have a higher kinetic energy than a short thick rod with the same mass and velocity.
The total kinetic energy of a rod can be influenced by its mass, velocity, and the external forces acting on it, such as friction or air resistance.
