how do newton's three law of motion apply to an automobile? please include friction in your discussion.
The automobile is standing at rest position when the engine is not started. When the engine of the automobile starts, then the engine produces a force that moves the automobile forward. This is direct consequence of the Newton’s second law. According to the Newton’s second law, the applied force is equal to the mass of the automobile and its acceleration. When the friction is present, the applied force is reduced by the friction force because this force always acts opposite to the motion of the auto mobile.
When the automobile reaches a high rate speed, they continue at that speed until any other external force is applied. This is due to the Newton’s first law.
When an automobile accelerates the engine transfer force to the tires, which push backward against the ground. The ground pushes back on the automobile. Here, tries apply a force on the ground is action force and the ground apply force on the tire is reaction force. So, this is the newton’s third law.
