Students’ Ability in Solving Physics Problems on Newtons’ Law of Motion

The ability to solve physics problems is one of the goals in learning physics and a part of the current curriculum demands. One of the physics problems that are often the focus of attention in learning is Newton’s law of motion. When solving physics problems on Newton’s law of motion, students need to utilize various aspects of certain abilities and rules. [1]

Question of the validity of newton‘s law at cosmic distances

Discrepancies in assumptions to explain the fact that in clusters of galaxies the kinetic energy is much greater than the potential energy, contrary to virial theorem predictions, lead to an assumption that the gravitational attraction at long distance is stronger than Newton’s law predicts. Ability of the proposed force and potential relations to explain some previously inexplicable astrophysical observations is discussed. [2]

Newton’s Gravitation Law is Wrong!

The Gravitational constant G of the universal law of gravitation by Isaac Newton, also used by Einstein in his general relativity, is discovered to composed from angular velocity coefficients forming an odd formula, in which the square of orbital velocity of a planet is multiplied by its radial distance, the product is divided by the mass of the sun; when the constant G in the gravity formula is substituted by these parameters, the formula is transformed into Centripetal Force (𝐹𝐶) formula, thus the formula for the gravitation force in essence represent a slightly distorted version of the Centripetal Force (𝐹𝐶), the development of an alternative theory to replace the current one is an important process that would lead one day to a better understanding of the physical world and a theory explaining the force governing stars and orbiting planets.

Quantum Corrections to the Newton’s Law from the Galilean Limit of Quantum Gravity

In this work the author derives the Galilean limit of the quantum gravity obtained by using the hydrodynamic approach. The result shows that the quantum interaction generates, in the limit of weak gravity, a non-zero contribution. The paper derives the small deviation from the Newtonian law due to the quantum gravity and analyzes the experimental features to validate the theoretical model. The work also shows that in the frame of the quantum gravity the equivalence principle between the inertial and gravitational mass can be violated in very extreme conditions. [4]

A Possible Exact Solution for the Newtonian Constant of Gravity

Compared with our knowledge of other fundamental constants, the exact value of the Newtonian constant of gravity (G) has long been enigmatic, and there is currently no officially accredited exact solution for G.[5]
