Issac newton discovered velocity.

"Speed" & "Velocity" are the same thing, they were not "invented" but discovered so to speak through Theoretical physics.
Velocity was first discovered by the ancient Greek philosopher Aristotle in the 4th century BC, as he laid down the foundation for the study of motion. He introduced the concept of natural motion, which included the idea of velocity, as part of his extensive writings on physics and natural philosophy.
The concept of velocity was developed by Galileo Galilei, an Italian scientist and mathematician, in the 17th century. He introduced the idea to describe the speed of an object in a specific direction, which is now a fundamental concept in physics.
The neutrino was recently discovered to have a velocity greater than that of light in a vacuum. This discovery was made in experiments such as OPERA where neutrinos were observed traveling faster than the speed of light, although those results were later retracted.
Galileo Galilei was the first to explain that heavy and light objects would fall the same way in a vacuum. Keep in mind, objects do not fall with 'velocity,' but with 'acceleration.'
Terminal velocity was first described by Sir Isaac Newton in the 17th century. He demonstrated that as an object falls through a fluid, such as air, it experiences drag force that increases as its speed increases. Eventually, the drag force will equal the force of gravity, causing the object to stop accelerating and reach a constant velocity known as terminal velocity.
Galileo Galilei is credited with discovering the difference between velocity and acceleration. He is known for his pioneering work in the field of kinematics, which laid the foundation for the modern understanding of motion.
The Gutenberg Discontinuity was discovered by Beno Gutenberg and Charles Francis Richter in the early 20th century. It is a boundary within the Earth's interior where seismic waves change velocity, indicating a change in composition between the outer core and the lower mantle.
The concept of escape velocity was developed by English physicist Sir Isaac Newton in the 17th century. He determined that any object, such as a spacecraft or a projectile, needs to reach a certain speed to break free from the gravitational pull of a celestial body like Earth.
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.
