Mechanics

Most of Galileo's investigations in physics had to do with the motion of bodies; these investigations lead him to the modern description of motion in terms of position and time. He realized that two important quantities that describe the motion of all bodies are velocity (which determines how position changes with time) and acceleration (which determines how velocity changes with time)

Two important defitnitions

Velocity: the rate of change of position (how position changes with time) Acceleration: the rate of change of velocity (how velocity changes with time)
