What did Aristotle say about force and motion?

What did Aristotle say about force and motion?

Basically, Aristotle’s view of motion is “it requires a force to make an object move in an unnatural” manner – or, more simply, “motion requires force” . After all, if you push a book, it moves.

What is the difference between Galileo and Newton’s views on motion?

Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest. This law is also the first of Isaac Newton’s three laws of motion.

What is the difference between Galileo and Newton’s findings regarding vertical and horizontal motion?

Therefore the point Newton is making is that the essential difference between Galileo’s natural steady speed horizontal motion and the natural accelerated vertical motion is that vertically, there is always the force of gravity acting, and without that–for example far into space–the natural motion (that is, with no …

What is the difference between Newton’s first law of motion with Galileo’s concept of inertia?

Newton’s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object’s mass.

What is Galilean motion?

Galilean invariance or Galilean relativity states that the laws of motion are the same in all inertial (or non-accelerating) frames. An inertial frame is a reference frame in relative uniform motion to absolute space. All inertial frames share a universal (or absolute) time.

How did Aristotle differentiate natural motion from violent motion?

According to Aristotle What are the two different types of motion? natural motion was thought to be either straight up or straight down because it was objects that would seek their natural resting place. Violent motion is imposed motion because is it the result of forces such as a push or pull.

What are the differences between the concepts of Aristotle in vertical horizontal and projectile motion?

Horizontal motion – Bodies need to be pushed or pulled to maintain horizontal motion. Projectile motion – An object is influenced by the downward force of gravity. Vertical motion – If two objects of different weight are dropped from a height both of them will hit the ground at the same time.

What is the difference between Aristotle’s and Galileo’s theory of motion?

What is the difference between Aristotle’S and galileo’s theory of motion? The difference between Aristotle’s idea of motion and Galileo’s idea of motion is that aristotle affirmed that once force is removed from an object it will stop while Galileo said an objects motion is stopped because of the force of friction.

How did Galileo contribute to the theory of inertia?

Aristotle did not believe in the void and thought the universe was a continuum. Galileo refined the concept of inertia. Galileo did not believe the ball came to a rest because it desired to be in its natural state. The theory of inertia says that an objects inertia will maintain its state of motion. So the ball should roll on forever.

Why are Galileo and Aristotle important to science?

3. ARISTOTLE AND GALILEO WERE TWO OF THE MOST IMPORTANT HISTORICAL FIGURES IN PHYSICS. THEY MAY HAVE HAD OPPOSING VIEWS REGARDING MOTION, BUT THEY BOTH HELPED SCIENCE PROGRESS. 4. ARISTOTLE • Classified motion as natural and violent.

What did Galileo say about the law of gravity?

Galileo disagreed. He said both objects would reach the ground about the same time. It is said that at the top of the tower, Galileo dropped two spherical objects, one heavier than the other, perhaps a cannonball and a musketball. Both hit the ground at about the same time, disproving Aristotle’s law of gravity.
