Final answer:

Grinders can be powered manually, electrically, or pneumatically.

Step-by-step explanation:

Grinders can be powered in different ways, including:

  1. Manually: Some grinders are powered by hand and require physical effort to operate. Examples of manually powered grinders include hand-cranked coffee grinders or pepper mills.
  2. Electrically: Many modern grinders are powered by electricity. They use an electric motor to spin the grindstone, which generates rotational kinetic energy. This energy is then converted into heat, light, sound, and vibration.
  3. Pneumatically: Pneumatic grinders are powered by compressed air. The air pressure drives a motor that spins the grindstone. These grinders are often used in industrial settings.
