Question

Mechanics and Newton's motion laws as ............... laws depended.
A. linear momentum
B. Energy conservation
C. Gravitational
D. Charge conservation

Answer 1

Hint: Concept of Newton's laws of motion are required to solve this question. The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.

Complete step by step solution:
Newton's 1st law: Every object in a straight line unless acted upon by a force.
Newton's 2nd law: The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass.
Newton's 3rd law: For every action, there is an equal and opposite reaction.

A. linear momentum: The product of an object's mass, m, and its velocity, \[v\] v, is the vector quantity known as linear momentum. It is represented by the letter "\[p\] ," which is also used to denote momentum. Please be aware that the body's momentum always points in the same direction as its vector of velocity. Because it is a conserved quantity, a system's overall momentum is always constant.

B. Energy conservation: A fundamental principle of physics and chemistry states that despite internal changes, the overall energy of an isolated system remains constant. It is the underlying principle of the first law of thermodynamics, which is most frequently stated as "energy cannot be generated or destroyed."

C. Gravitational:Newton’s law of gravitation, states that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. In symbols, the magnitude of the attractive force \[F\] is equal to \[G\] (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (\[{m_1}\] and \[{m_2}\] ) and divided by the square of the distance \[r\]:\[F\; = \;\dfrac{{G({m_1}{m_2})}}{{{r^2}}}\]

D. Charge conservation: Charge conservation in physics states that an isolated system's total electric charge never changes. The universe's net electric charge, which is equal to the sum of positive and negative charges, is always preserved.

Hence, the correct option is C.

Note:With the exception of very small entities like electrons or those moving nearly at the speed of light, Newton's equations continue to accurately describe nature. Newton's rules are what quantum mechanics and relativity come down to for larger or slower moving objects.
