Hint: In order to answer this question, first we will discuss the first law of motion and then we will discuss the mechanism in the first law of motion. And atlast we will discuss why the first law of motion is also known as Galileo's law of inertia.

Complete answer:
Galileo's law of inertia is another name for the first law of motion. Newton's First Law of Motion states that until an unbalanced force acts on it to change its condition of rest or uniform motion, a body at rest will remain at rest and a body in motion will remain in uniform motion.

The law of inertia, often known as Newton's first law, states that if a body is at rest or moving in a straight line at a constant speed, it will remain at rest or continue to move in a straight path at a constant speed until it is acted with by a force. Galileo Galilei first proposed the law of inertia for horizontal motion on Earth, and René Descartes later generalised it.

Prior to Galileo, it was considered that all horizontal motion required a direct cause, but Galileo reasoned from his tests that a body in motion would stay in motion unless a force (such as friction) brought it to a halt. The first of Isaac Newton's three laws of motion is this one.The principle of inertia is the starting point and fundamental assumption of classical mechanics, yet it is not immediately apparent to the untrained eye.

Objects that are not being pushed tend to come to a halt in Aristotelian mechanics and in everyday life. Galileo derived the law of inertia from his studies with balls rolling down inclined surfaces. The principle of inertia was key to Galileo's major scientific task: he had to explain how it is conceivable that we do not perceive the Earth spinning on its axis and orbiting the Sun if it is spinning on its axis and orbiting the Sun. The theory of inertia aids in the answer: we are in motion with Earth, and our natural impulse is to maintain that motion, thus Earth appears to be at rest to us.

Note: Unless an external force occurs on an object, it remains in a state of uniform motion. The product of mass and acceleration is force. There is an equal and opposite reaction to every action. The law of inertia is another name for Newton's first law of motion.
