Final answer:
Isaac Newton's laws of motion include Newton's first law, which is about objects remaining in a state unless affected by an external force; Newton's second law, which relates force, mass, and acceleration; and Newton's third law, which asserts that every action has an equal and opposite reaction.
Step-by-step explanation:
Isaac Newton's contributions to science include his three fundamental laws of motion that describe the behavior of moving bodies. These laws are essential in the field of classical mechanics, which is a branch of Physics.
Newton's First Law of Motion
Newton's first law, often referred to as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by a net external force. This implies that in the absence of external forces, the state of motion of an object does not change.
Newton's Second Law of Motion
Newton's second law describes the relationship between an object's mass, the force applied to it, and its acceleration. It can be formulated as: F=ma, where F is the force applied, m is the mass of the object, and a is the acceleration that results.
Newton's Third Law of Motion
Newton's third law states that for every action, there is an equal and opposite reaction. This law explains the nature of forces when two bodies interact with each other, meaning that forces always come in pairs of equal magnitude and opposite direction.
