Why did Galileo use a thought experiment instead of working with real objects

Physics
1 answer:
Alja [10]3 years ago
5 0

Answer:

Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill.

Suppose that the opposite hill was horizontal. Would the ball's motion continue forever along the tangent, or forever parallel to the Earth's surface

Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity.

Newton took this as his first law of motion.

If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, what's the average velocity of t
Ronch [10]

Since the acceleration is constant, the average velocity is simply the average of the initial and final velocities of the body:

v_{avg} = \frac{v_f+v_i}{2}=\frac{30 m/s+13 m/s}{2}=21.5 m/s

We can proof that the distance covered by the body moving at constant average velocity v_{avg} is equal to the distance covered by the body moving at constant acceleration a:

- body moving at constant velocity v_{avg}: distance is given by

S=v_{avg}t = \frac{v_f+v_i}{2}t

- body moving at constant acceleration a=\frac{v_f-v_i}{t}: distance is given by

S=v_i t+ \frac{1}{2}at^2 = v_i t + \frac{1}{2}\frac{v_f-v_i}{t}t^2=(v_i+\frac{1}{2}(v_f-v_i))t=\frac{v_f+v_i}{2}t

satela [25.4K]
All forms of matter are comprised of atoms. Wind in itself is the movement of particles(air). Wind does not have particles since it is an action and not a form of matter.

Why does a crumpled paper land before a flat sheet of paper?
Nitella [24]

Answer:

The crumpled paper hits the ground first due to air resistance. The crumpled paper has less surface area than the flat paper, therefore the crumpled paper hits first.

I hope this helped. If you could mark brainliest that would be greatly appreciated.
