1.	Define the following:1. Vibration2. Heat energy
Answer» ong>Answer: Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when ALMOST any physical system is displaced from its equilibrium condition and ALLOWED to respond to the forces that TEND to restore equilibrium. Thermal energy (also CALLED heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and COLLIDE with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
