Homework Statement
I just wanted to know if I was correct, when dealing with a Newton law problem that has components.
Ʃfx=0 and ƩfY = zero
However when we add the forces together then we can use Ʃf=ma
thanks
Newton's first law states that 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. The second law states that the force acting on an object is equal to its mass multiplied by its acceleration. The third law states that for every action, there is an equal and opposite reaction.
Mass is the amount of matter an object contains, while weight is the force of gravity acting on an object. In Newton's second law, mass is a factor in determining an object's acceleration, while weight is not directly related to the laws of motion.
Newton's laws are used to explain and predict the behavior of objects in motion. They are applicable to many real-world situations, such as the motion of vehicles, the flight of airplanes, and the movement of celestial bodies.
Newton's laws are fundamental principles in the field of physics and have played a crucial role in understanding the behavior of objects in motion. They have also led to developments in technology, such as the invention of the steam engine and the modern automobile.
No, Newton's laws are considered to be universal and have been extensively tested and proven through observations and experiments. However, they are not applicable in certain extreme conditions, such as at the speed of light or in the subatomic world.
