Key Stage 1
Meaning
A motor is something that spins when electricity goes through it.
Key Stage 2
Meaning
A motor is component in a circuit that spins when electricity flows through it.
About Motors
- A motor has a part that stays still and a part that spins around.
- The motor will get faster when the electrical current increases.
 |
 |
| A motor. | The symbol for a motor. |
Key Stage 3
Meaning
A motor is component in a circuit that spins when electricity flows through it.
About Motors
- A motor has a part that stays still and a part that spins around.
- The motor will get faster when the electrical current increases.
|
|
| A motor. | The symbol for a motor. |
Key Stage 4
Meaning
The symbol for a motor.
A motor is component in a circuit that spins when electricity flows through it.
About Motors
- In a motor electrical work is done to move an object against a force. This may be lifting the object in which electrical work transfers energy into the gravitational potential energy store or it may be accelerating an object transfers energy into the kinetic energy store.
- A motor can apply a greater force when the electrical current increases.
Energy Transfers
Accelerating
- In a motor electrical work can be done to accelerate an object.
- While the object is accelerating energy is transferred into the kinetic energy store of the object.
- The motor also does electrical work against friction.
- Friction causes energy to be transferred into the thermal energy store of the motor and object.
Lifting
- In a motor electrical work can be done to lift an object.
- While the object is being lifted energy is transferred into the gravitational potential energy store of the object.
- The motor also does electrical work against friction.
- Friction causes energy to be transferred into the thermal energy store of the motor and object.
