Your car breaks down as your friends help you push it it begins to move and speed up is this Newton's first law second Law or third law
This scenario corresponds to Newton's first law of motion.
Newton's first law, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force. In this case, the external force is the initial push from your friends, which causes the car to overcome its initial state of rest and start moving.
It is important to note that this scenario does not involve Newton's second or third law. Newton's second law relates the acceleration of an object to the net force acting on it and its mass. Newton's third law states that for every action, there is an equal and opposite reaction.
The scenario you described can be explained by Newton's second law of motion. Newton's first law states that an object at rest tends to stay at rest, and 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. However, in your scenario, the car was initially at rest (as it broke down), but it began to move and speed up when your friends pushed it.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simple terms, when a force is applied to an object, it will accelerate in the direction of that force. In this case, your friends pushed the car, applying a force on it, starting its movement, and causing it to speed up.
To determine whether this situation corresponds to Newton's first law, second law, or third law, we need to understand the fundamentals of these laws:
1. Newton's first law (Law of Inertia): An object at rest will remain at rest, and an object in motion will continue moving at a constant velocity, unless acted upon by an external force.
2. Newton's second law (Law of Acceleration): The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. It can be expressed as the equation F = ma, where F is the force, m is the mass of the object, and a is the acceleration.
3. Newton's third law (Law of Action-Reaction): For every action, there is an equal and opposite reaction. When one object exerts a force on a second object, the second object simultaneously exerts a force of equal magnitude in the opposite direction on the first object.
In the given scenario, as your friends help push the car, it begins to move and speed up. Here's how the laws apply:
- Newton's first law: If the car remained stationary and did not speed up, it would be an example of the first law. However, since it starts to move and accelerate, we can exclude the first law.
- Newton's second law: To determine if the situation aligns with the second law, we need to know if the car's acceleration is proportional to the net force applied and inversely proportional to its mass. More information is required to apply this law.
- Newton's third law: When your friends push the car, they exert a force on it. According to the third law, the car exerts an equal force in the opposite direction on your friends. However, this law only explains the interaction between the car and your friends, not how the car itself accelerates.
Therefore, based on the limited information provided, we cannot definitively conclude whether this situation corresponds to Newton's first law, second law, or third law.
