Energy Transfer

The most common energy transformation is the transformation between these two:

• air & water
• kinetic energy & potential energy
• water & soil
• potential energy & gravitational potential energy

What is energy transformation?

• a change of energy from one form to another
• when energy gets more energy added to it
• when energy gets destroyed
• a change in intensity

Any object that rises and falls experiences a change in:

• gravitational potential energy & kinetic energy
• release of energy
• size
• color

Whenever a moving object experiences friction, some of its kinetic energy is turned to...

• mechanical energy
• potential energy
• thermal energy
• light energy

Friction happens in these examples, except for...

• when you rub your hands together
• a spinning top is rubbing the floor
• a rocket traveling through space
• tires of a moving car on the road

As a top spins, it encounters friction with two of these...

• floor & temperature
• floor & air
• air & temperature
• temperature & speed

Your body transforms the chemical energy in food into...

• nuclear energy
• gravitational potential energy
• solar energy
• mechanical energy

According to the Law of Conservation of Energy...

• energy changes form
• energy can be created and destroyed
• energy flows from one material to the next
• energy cannot be created or destroyed

All are examples of energy transformation that regularly goes from kinetic to potential and back and forth in a repeated pattern, except...

• Juggling
• A soccer ball kicked once
• See-Saw
• Swing
