# Identifying Newton's Laws in Physics-B Situations

• 8parks11
In summary, Newton's three laws of motion state that an object will remain at rest or in motion unless acted upon by an external force, force is equal to mass times acceleration, and for every action there is an equal and opposite reaction. To identify which law is being applied, one can consider if the object is at rest, if there is a net force, and if the object is accelerating. These laws can be applied to most situations, but may not accurately describe extreme conditions. In everyday life, these laws can be seen in activities such as driving a car or throwing a ball. They have been proven to hold true in countless experiments and observations.

does anybody know where I can find a LOT of situations where I have to identify which law of Newton it fits to?

If not, can somebody give me situations in which I have to indentify?
This is AP physics-B level so something not that convoluted

Thanks

Come again?

What are you talking about? Just look around around you. You can apply it to practically EVERYTHING!

## 1. What are Newton's three laws of motion?

Newton's three laws of motion are: (1) An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force. (2) The force acting on an object is equal to its mass multiplied by its acceleration (F=ma). (3) For every action, there is an equal and opposite reaction.

## 2. How can I identify which of Newton's laws is being applied in a given physics situation?

To identify which of Newton's laws is being applied, you can ask yourself the following questions: (1) Is the object at rest or in motion? (2) Is there a net force acting on the object? (3) Is the object accelerating? By answering these questions, you can determine which of Newton's laws is at play.

## 3. Can Newton's laws be applied to all objects and situations?

Yes, Newton's laws can be applied to all objects and situations, as long as the objects are not moving at speeds close to the speed of light and the forces involved are not extremely strong, such as in the case of subatomic particles.

## 4. How do Newton's laws relate to everyday life?

Newton's laws play a role in many everyday activities, such as driving a car, throwing a ball, and riding a bike. For example, when you press the gas pedal in a car, you are applying a force that causes the car to accelerate, in accordance with Newton's second law.

## 5. Can Newton's laws be broken or violated?

No, Newton's laws are fundamental laws of physics and have been proven to hold true in countless experiments and observations. However, there are some rare situations, such as in extreme conditions like the speed of light or near black holes, where these laws may not accurately describe the behavior of objects.
