Conservation of energy means that:

• Energy CAN be created but CANNOT be destroyed

• Energy CANNOT be created and CANNOT be destroyed

• Energy CANNOT be created but CAN be destroyed

In the picture above, kinetic energy is being converted INTO potential energy (Kinetic --> Potential) from:

• Point A to point B

• Point B to point C

• Energy is not being converted

In the picture above, potential energy is being converted INTO kinetic energy (potential --> kinetic) from:

• Point A to point B

• Point B to point C

• Energy is not being converted

In the picture above, as the car moves from point A, to point B and finally to point C, the TOTAL energy of the car:

• Decreases from point A to point B, then increases from point B to point C

• Increases from point A to point B, then decreases from point B to point C

• Stays the same because energy is conserved, but is converted between potential and kinetic energy
