What is the name for the inherent property of matter to retain its state of rest or uniform motion in a straight line unless acted upon by external forces?
Physics in the medieval Islamic world to its natural motion. So he concluded that continuation of motion is attributed to the inclination that is transferred to the object, and that object will be in motion until the mayl is spent. He also claimed that projectile in a vacuum would not stop unless it is acted upon. This conception of motion is consistent with Newton's first law of motion, inertia. Which states that an object in motion will stay in motion unless it is acted on by an external force. This idea which dissented from the Aristotelian view was basically abandoned until it was described as "impetus"
Newton's laws of motion both its speed and the direction of its motion are constant. The first law can be stated mathematically when the mass is a non-zero constant, as, Consequently, This is known as "uniform motion". An object "continues" to do whatever it happens to be doing unless a force is exerted upon it. If it is at rest, it continues in a state of rest (demonstrated when a tablecloth is skilfully whipped from under dishes on a tabletop and the dishes remain in their initial state of rest). If an object is moving, it continues to move without turning or changing its
