We learned about heat as a form of energy change. Heat occurs when bonds are formed, not when bonds are broken in chemical reactions. Exothermic- when energy leaves a system. Endothermic- when energy enters a system. Endothermic vs Exothermic

Types of Energy

• Kinetic Energy- energy of motion
• Radiant Energy- energy from the sun or solar energy
• Thermal Energy- energy associated with the random motion of atoms and molecules 
• Chemical Energy- energy stored within the structural units of chemical substances
• Potential Energy- energy stored or energy of position
