Aristotle's ideas were believed to be true from 500 BC to 1600 CE. That's about 1,100 years of false knowledge. What Aristotle taught, appeared to be correct because it seemed obvious, but not all things are obvious.
Aristotle's view on motion seems to make sense. Unfortunately, it isn't correct. But because his theories appeared to make sense, they became popular and well accepted for a very long time. The key ideas that Aristotle tried to teach were:
All motion on the Earth is linear .
All motion in the heavens (outer space) is curved .
The speed at which an object falls is directly related to the mass of an object .
Motion could be considered in two main factions: natural and violent.
Motion continues so long as there is only an applied motion to an object. Removing the motion stops the object.
It would take a man named Galileo to start the wheels of change in this field of knowledge called physics.
Galileo, unlike Aristotle, proved that motion to the Earth does not depend on the weight of an object. All objects fall to the ground at the same speed. So you see, the speed at which an object falls at has nothing to do with the mass of the object. All objects that are released from the same starting point reach the ground in the same time. Galileo proved Aristotle wrong. He proved the concept of what is called force and mass.
Aristotle's contribution to force was primarily in the realm of philosophy and physics, where he developed the concept of natural motion and violent motion. He believed that objects had a natural tendency to move towards their proper place in the universe, and that an external force was required to cause violent motion. Aristotle's ideas on force laid the foundation for later developments in classical mechanics.

Aristotle was a famous Greek philosopher. He examined the nature of matter, space, time, and motion and proved that infinite linear motion and voids could not exist on Earth. He also reasoned that infinite velocities could not exist, and that time and movement are continuous and inseparable.
Aristotle enjoyed studying motion because he really enjoyed learning about why different things worked.
Aristotle advocated two classes of motion: natural motion, which is inherent to objects and includes vertical motion (up or down), and violent motion, which is caused by an external force and includes horizontal motion (push or pull).
Aristotle believed v = k(F/R) where speed is proportional to motive force, and inversely proportional to resistance.
Aristotle's dynamic motion theory was proven wrong with the advancements in physics and the development of Newton's laws of motion. Newton's laws provided a more accurate description of how objects move and interact with each other, which contradicted Aristotle's ideas about motion and force. Additionally, the observations and experiments of scientists like Galileo further disproved Aristotle's theories on motion.
Aristotle classified motion into natural motion and violent motion. Natural motion was intrinsic to an object's nature, such as an apple falling from a tree. Violent motion was caused by an external force acting on an object, like pushing a ball.
Unmoved mover. The unmoved mover in Aristotle's philosophy is the ultimate cause of all motion and change in the universe, while itself remaining unchanged and unaffected.

Isaac Newton is credited with disproving Aristotle's laws of motion. He did so by introducing his three laws of motion, which provided a more accurate explanation of how objects move and interact with one another compared to Aristotle's principles. Newton's laws formed the foundation of classical mechanics.
