Explain how Newton’s 1st law of motion applies to a car driving trough a town
Newton's 1st law of motion, often referred to as the law of inertia, states that an object at rest tends to stay at rest, while an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
When a car is driving through a town, it is subject to various external forces that may affect its motion. For instance, when the car starts from rest at a traffic signal, it remains at rest until an external force, such as pressing the accelerator pedal, is applied. This is because of the inherent tendency of the car to stay at rest due to inertia.
Once the accelerator is pressed, the car experiences a force in the forward direction, overcoming the inertia and causing it to move. Now, according to Newton's 1st law, the car will continue to move forward with the same speed and in the same direction (ignoring any air resistance or other external forces) until another external force acts on it.
As the car moves through the town, it encounters various forces that can alter its motion. For example, if the driver applies the brakes, a force is exerted in the opposite direction of motion. This force acts as an external force, slowing down the car. Similarly, if the driver turns the steering wheel, the car changes its direction due to an external force known as the centripetal force.
Overall, Newton's 1st law applies to a car driving through a town by explaining how the car's motion, both in terms of speed and direction, is influenced by the external forces acting upon it. The law emphasizes that the car will continue moving until a force is applied to change its motion, and it will resist any change in its state of motion due to inertia.
