Did Aristotle or Galileo rely on experiments?
Who relied on experiment, Aristotle or Galileo? Dropped 2 weights from tower, both fell at same rate, disproving Aristotle’s ideas on motion. Galileo let a ball roll down one incline and up another.

What 2 main ideas of Aristotle did Galileo discredit?
What two main ideas of aristotle did Galileo discredit? Forces are needed to keep an object in motion, and heavier objects fall faster.
How did Galileo discredit Aristotle’s ideas on motion what experiments did he do )?
How did Galileo discredit Aristotle’s assertion that a force is needed to keep objects moving. Galileo’s experiments with rolling balls along surfaces tilted at different angles and his findings about motion helped him to discredit Aristotle’s theory of motion. As long as no forces act against it. Like friction.
How did Galileo prove gravity?
According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. As the atoms rose and fell, both varieties accelerated at essentially the same rate, the researchers found.
Would a brick or feather fall faster?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.
What falls faster a pound of feathers or a pound of bricks?
The bricks are more compact and dense and would fall faster than the pound of feathers. The pound of feathers would have so much more surface area and lower density that they would fall much slower than the bricks.
Why does a hammer hit the ground before a feather?
Gravity accelerates both objects at the same rate, but another factor comes into play: air resistance. The feather is slowed down more by the air and floats down gently, while the hammer crashes straight to the ground.
Does acceleration increase with mass?
As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration. Therefore, mass is inversely proportional to acceleration.
What is the relationship between force mass and acceleration?
It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
How does the mass affect acceleration?
Objects with a greater mass will fall faster (with a greater acceleration?) An objects forward motion will change the rate at which objects fall.
What is the relationship between mass and acceleration when force is constant?
Newton’s second law of motion states that acceleration is directly proportional to net force when mass is constant… and that acceleration is inversely proportional to mass when net force is constant…
How long will it take a force of 10n to stop a mass of 2.5 kg which is moving at 20m S?
Therefore, the object will take 5 sec to stop a mass of 2.5 kg which is moving at 20m/s.
What is the difference between mass and force?
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.
Why is weight in kg?
Weight, instead, corresponds to the resultant force of the action exerted by gravity of the Earth (in our case) on the mass of a body, and its measuring unit is Newton (N) at the ISU. Thereby, weight of an object becomes mass in an easy way. And that’s how we “weight” in kg.
What is the weight of 1 kg of mass?
Answer. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.
Is height a force?
The change in velocity is very small, and the change in time is small. When you hit the ground falling from 50 meters, the change in velocity is very large, and the change in time is small. This means the hitting force goes up, or is proportional to the initial height. Bigger fall, results in a bigger force.
Which dominated Galileo’s way of extending knowledge − − philosophical discussion or experiment?
Experiments
What were the two main classifications of motion in Aristotle’s view of science?
Aristotle classified motion into two kinds: natural motion and violent motion. Did Aristotle believe that forces are necessary to keep moving objects moving, or did he believe that, once moving, they would move by themselves? Aristotle believed forces were necessary.
What are Aristotle’s two main classifications of motion?
types: natural motion and violent motion. Heavy things fall and very light things rise.
What is the prime mover Aristotle?
‘that which moves without being moved’) or prime mover (Latin: primum movens) is a concept advanced by Aristotle as a primary cause (or first uncaused cause) or “mover” of all the motion in the universe. As is implicit in the name, the unmoved mover moves other things, but is not itself moved by any prior action.
What is Newton’s second law class 9?
Newton’s Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. ie., F=ma. Where F is the force applied, m is the mass of the body, and a, the acceleration produced.
