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.
