hello can some one help me, post a simplified version of Newton's 3 laws of motion and some examples thank you very much :)
Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion with a constant velocity unless acted upon by an external force. 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. Newton's third law of motion states that for every action, there is an equal and opposite reaction.
Newton's laws of motion can be observed in everyday life, such as when a ball rolls down a hill (first law), a car accelerates when the gas pedal is pressed (second law), and a rocket launches off the ground (third law).
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. According to Newton's second law of motion, an object's mass affects its acceleration, while its weight affects the force needed to accelerate it.
Before Newton's laws of motion, the prevailing belief was that objects needed a continuous force to remain in motion. However, Newton's laws explained that objects in motion will remain in motion unless acted upon by an external force, revolutionizing the understanding of motion and providing a foundation for modern physics.
While Newton's laws of motion provide a good approximation for most everyday situations, they do not hold true in extreme conditions such as at the speed of light or in the presence of strong gravitational fields. These situations require the use of more advanced theories such as Einstein's theory of relativity.
