## What did Galileo say about motion?

Galileo was correct in his statement that objects in motion tend to stay in motion, but he seemed to believe that inertial motion moved equidistant from the center of the Earth.

Descartes was the first one to correctly state that an object in motion continues its motion in a straight line..

## What are the two types of motion according to Aristotle?

In the Metaphysics, however, Aristotle draws a distinction between two kinds of potentiality. On the one hand, there are latent or inactive potentialities. On the other hand, there are active or at-work potentialities. Accordingly, every motion is a complex whole, an enduring unity which organizes distinct parts.

## Who said that impetus keeps a body moving?

Jean BuridanIn the 14th century, Jean Buridan postulated the notion of motive force, which he named impetus. When a mover sets a body in motion he implants into it a certain impetus, that is, a certain force enabling a body to move in the direction in which the mover starts it, be it upwards, downwards, sidewards, or in a circle.

## How is motion described?

In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. … One can also speak of motion of images, shapes and boundaries.

## What is motion with respect to quality?

Motion with respect to quality. It refers to the passive quality in virtue of which a thing is said to be acted on or to be incapable to be acted on. 2. Motion with respect to quantity. If the motion in the complete magnitude is increased, motion in the contrary direction is decreased.

## What is the natural motion?

Aristotle’s Laws of Motion – Some motions maintain themselves – these are called natural motion. An example of a natural motion is a falling rock. – Objects seek their natural place. For the rock, this natural place is the ground. – Fire rises, it is seeking its natural place in the sky (or something like that).
