Forms of Energy Review

An energy transformation occurs when

• one form of energy changes to another form of energy in the same object
• the form of energy remains the same type but is moved from one object to another
• matter transforms to make energy in nuclear reactions
• energy is created or destroyed during a chemical reaction 

Energy cannot be created or destroyed in any reaction. This law is known as......

• Energy Transfer 
• Energy Transformation 
• Conservation of Energy 
• Gravitational Limits
