About Driving Force
- Driving force is a force so it is measured in Newtons.
- Driving force is a contact force because an engine needs to make contact against a surface and use friction to accelerate the motion of the object.
- Driving Force can cause a vehicle to accelerate and can act to counter air resistance to keep a vehicle travelling at a constant speed.
Example
 |
| The driving force of the car acts in the direction of motion. |

About Driving Force
- Driving force is a force so it is measured in Newtons.
- Driving force is a contact force because an engine needs to make contact against a surface and use friction to accelerate the motion of the object.
- Without friction between two surfaces there cannot be a driving force.
- Driving Force can cause a vehicle to accelerate and can act to counter air resistance to keep a vehicle travelling at a constant speed.
Example
|
| The driving force of the car acts to push the road backwards. The road provides a reaction force to accelerate the car forwards. |
