what force causes an automobile to move
Answers
Friction between the tires and ground (coupled with elastic forces in the tire) causes an automobile to move.
It is all based on Newton's Third Law of motion "Every force has an equal but opposite reaction". The force torque turns the tire on a car and the tire grips and the road pushes it forward by applying equal opposite reaction force to the torque. After that the momentum and force applied keeps it going.
In other automobiles like airplanes, a propeller works as a rotating wing. It generates thrust by rapidly pushing air backwards, creating high pressure behind the propeller, and low pressure in front of it. This leads to a net forward force on the propeller.
Force: A force is any interaction will change the motion of an object. Acceleration is caused by force acting on a body.
There are many types of forces. Some of them are,
- Frictional force
- Tension force
- Normal force
- Applied force
- Gravitational force
For the movement of an automobile,
- Gravitational force keeps the automobile on its wheels
- Applied force by the engine makes the automobile to move
- Frictional force is acted on the road by the tyres.
