- Energy
- Energy stores
- GPE-dropping a bouncy ball
- Kinetic-a person walking
- Electrical-food mixer
- EPE-rubber band
- Sound-speaker
- Chemical-battery
- Thermal-burning fire
- ENERGY CAN'T BE DESTROYED OR CREATED IT CAN ONLY BE TRANSFORMED FROM ONE FORM TO ANOTHER
- A torch being switched on
- A kettle being boiled
- Sometimes we get unwanted energy
- When you bounce a ball it makes a sound, which we don't need
- A pendulum motion
- As the pendulum swings down and towards the centre ,it's GPE store decreases and the kinetic energy increases
- As the pendulum moves up and away from the centre, it's GPE store increases and it's kinetic store decreases
- Conservation of energy
- In a closed system energy is conserved
- Energy is also transferred through heat due to friction
- chemical-EPE-GPE-sound
- muscles-until the rope straightens out-when the person starts to bounce back up
- Energy stores
