| Front | What do exchange particles do? |
| Back | Carry energy and momentum between the particles experiencing the force. Each fundamental force has its own exchange particles. |
| Front | In the magnetic flux density practical (magnets and mass balance), explain what would happen to a graph of mass against current if the wire doesn't go through the magnets |
| Back | - B decreases because less field lines pass through the wire- Intercept remains the same because that's the initial mass- The gradient is less steep because the force won't charge as much with current |
| Front | What is an application of a thermistor in circuits? |
| Back | As a temperature sensor, which can trigger an event to occur once the temperature drops or reaches a certain value. |
