| Question | Answer |
|---|---|
| why do larger balls bounce higher than smaller ones? | larger balls bounce higher because they have greater mass and volume, allowing them to retain more kinetic energy and overcome air-resistance better. |
| what's kinetic energy? | energy of motion |
| what's potential energy? | Stored energy that has not been used, and has the potential is become kinetic energy. |
| Voltage (V) | The push that moves electrons, measured in volts |
| Current (I) | The flow of electric charge, measured in amperes |
| Resistance (R) | Opposition to the flow of electrons, measured in ohms |
| energy efficiency | using less energy to provide the same service or output, effectively reducing energy waste. |
| what does the law of conservation of energy state? | That energy cannot be destroyed or created, it can only be transformed or transferred from one form into another. |
