The fact that Voyager 10 continues to speed out of the solar system even though its rockets have no fuel, is an example of Newton's first law.
Sir Isaac Newton is a British mathematician, physicist, astronomer, alchemist, theologist, author, one of the greatest mathematicians and physicists of all time, and one of the most influential scientists. Widely recognized as a person. He was a key figure in the philosophical revolution known as the Enlightenment.
Isaac Newton is best known for his discoveries in optics (composition of white light) and mathematics (calculus). His best known is the formulation of the three laws of motion, which are the basic principles of modern physics.
Newton's first law states that a stationary or uniformly moving object remains straight unless its state is changed by the action of an external force.

Metals are good conductors because the molecules that are inside the metal are tightly packed together. This is why the heat moves through the metal quickly.
C.) spinning of an object on its axis :)
It is possible to demonstrate that the maximum distance occurs when the angle at which the projectile is fired is
.
In fact, the laws of motions on both x- and y- directions are
From the second equation, we get the time t at which the projectile hits the ground, by requiring
, and we get:
And inserting this value into Sx(t), we find
And this value is maximum when
, so this is the angle at which the projectile reaches its maximum distance.
So now we can take again the law of motion on the x-axis
And by using
, we find the value of the initial velocity v0:
True, the electric field produced by a uniform, infinite plane of charge does not depend on the distance from the plane.
<h3>
What is electric field?</h3>
Electric field is the region of space at which electric force is felt.
E = kq/r²
where;
- r is the distance of the charge
at infinite plane, r → ∞, and E = 0
Thus, the electric field produced by a uniform, infinite plane of charge does not depend on the distance from the plane.
