When the bullet is travelling, it has a kinetic energy store because it is moving. When it hits the wood, the bullet does mechanical work on the wood. This transfers energy from the bullet’s kinetic energy store to the thermal energy store of the wood, bullet and surroundings.

A rifle can shoot a 0.0042 kg bullet at a speed of 965 m/s. Find the kinetic energy of the bullet. An automobile to be transported by ship is raised 7.3 m above the dock.
Muzzle energy - Wikipedia
Kinetic Energy. Kinetic energy (KE, Ek) is the energy of an object due to its translational motion. This is apparent from its formula. When the object is considered to be a particle, The kinetic energy of a 10-kg mass traveling at 1 m/s is. The unit of energy is the joule, as mentioned previously. Work-Kinetic Energy Theorem
