Question

Why is newton's first law of motion law and not theory?

Answer 1

Newton's first law of motion is called a law because it has been repeatedly tested and verified by experiments. It has never been found to be incorrect. Here are five reasons why Newton's first law of motion is considered a law:

1. It has been tested and verified by experiment.
2. It is consistent with other laws of physics.
3. It is simple and easy to understand.
4. It is widely applicable to a wide range of phenomena.
5. It has been used to make accurate predictions about the behavior of objects.

Here are some examples of how Newton's first law of motion has been used to make accurate predictions:

• We can predict that a ball will continue to roll in a straight line unless it is acted upon by an external force, such as friction.
• We can predict that a car will continue to travel at a constant speed unless it is acted upon by an external force, such as the force of friction from the road.
• We can predict that a planet will continue to orbit the sun in a circular path unless it is acted upon by an external force, such as the force of gravity from another planet.

Newton's first law of motion is a fundamental law of physics that has been used to make accurate predictions about the behavior of objects for centuries. It is a testament to the power of science that we can use our understanding of the laws of physics to make predictions about the world around us.
