Newton’s ideas on physics “won”, and aristotle’s ideas were kicked out of science and over into history. why?

1 answer:

4 0

Basically, Newton's ideas matched up better with experiments and observations about the natural world than Aristotle's did. Newton gave a rigorous mathematical framework that made very specific predictions about our world, while Aristotle in general made more comparative laws, that even when true were less useful than the certainty Newton's laws gave us. Many of Newton's laws have been found to be at least partially incorrect now, for instance his laws of motion fall apart at speed nearing the speed of light, his laws of gravity fall apart when talking about more than two objects and in the presence of large gravitational fields that are close together, and Newton's law of cooling is just untrue in general (though can make some approximations in narrow temperature ranges).

If displacement covered by a particle is zero then distance cover by it

sleet_krkn [62]

Answer:

When displacement is zero, the particle may be at rest, therefore, distance travelled = 0.

Again, when displacement is zero, the final position matches with the initial position after some time, but the distance travelled will not be zero.

You drop a rock down a well that is 5.4 m deep. How long does it take the rock to hit the bottom of the well?

Natali5045456 [20]

Equation of motion:

$y_{f}=y_{o}+v_{o}t+ \frac{1}{2} at^{2}$

Since initial velocity is zero, the second term goes away:

$y_{f}=y_{o}+0+ \frac{1}{2} at^{2}$

$y_{f}=y_{o}+\frac{1}{2} at^{2}$

$y_{f}-y_{o}= \frac{1}{2} at^{2}$

$y_{f}-y_{o}=5.4m$

$5.4m= \frac{1}{2} at^{2}$

$\frac{2(5.4m) }{a} = t^{2}$

$a = g = 9.81 \frac{m}{ s^{2}}$

$\frac{2(5.4m) }{9.81 \frac{m}{ s^{2} } } = t^{2}$

$1.1 s^{2} = t^{2}$ $\sqrt{1.1 s^{2}} = \sqrt{t^{2}}$

 $t = 1.05s$

1.A body of certain mass is kept at a height of 15m from the ground, taking the value of g as 10m/s find out the mass of the bod

ehidna [41]

Answer:

1.#potential energy = PE, m = mass in kg, g = force of gravity, h= vertical height above the ground. ** means to the power of ie exponent. * means multiply.

PE = mgh

300 = m(10)(15)

m = 300/(10)(15)

m= 2kg

2. KE = 1/2 mv**2

= 1/2(50)(50)**2

= 2500 joules

Explanation

Is as in solution
