Newton's Laws

These are flashcards if you want to precisely memorise Newtons Laws

What is Newton’s First law of Motion?

Unless acted upon by an external force, an object at rest remains at rest, and an object in motion continues in motion with the same velocity (constant speed and direction). This is also known as the law of inertia.

What is Newton’s Second Law of Motion?

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F=ma. This law explains how the motion of an object changes when a net force is applied. This law states that an object's acceleration increases with greater force and decreases with greater mass. In simpler terms, this means that the harder you push or pull an object, the faster it will speed up, but if the object is heavier, it will not accelerate as quickly.

What is Newton’s Third Law of Motion?

For every action, there is an equal and opposite reaction, meaning that forces always occur in pairs. If object A exerts a force on object B, then object B simultaneously exerts a force on object A that is equal in magnitude and opposite in direction.

Who is Sir Isaac Newton?

An english physicist and mathematician, widely recognised as one of the most influential scientists of all time, known for formulatin the laws of motion and universal gravitation.

What is the title of Isaac Newton’s Seminal work where he published his law of motion and universal gravitation?

Philosophia Naturalis Principia Mathematica (Mathematical principles of Natural Philosophy) or in simpler terms Principia.

Besides the laws of motion, what other significant contributions did Isaac Newton Make to science and mathematics?

He developed the theory of universal gravitation, co-invented calculus, and made fundamental discoveries in optics, including the decomposition of white light into a spectrum of colors.

Why are Newton’s Law of Motion important?

They form the foundation of classical mechanics, explaining how objects move and interact with forces, which is essential for understanding the physical worl and many technological developments.
