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.
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.
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.
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.
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.
