There are 2 types of acceleration
... You are in Uniform Circular Motion (UCM for short). Things to remember about UCM: UCM is circular motion at a constant speed. The only acceleration there is will be centripetal acceleration. The centripetal acceleration always points toward the center of the circle. ALWAYS! Since the acceler ...

... a) First of all, which way is the box going to go? You have to figure that out first. To do that compare the x-component of F2 to the x-component of F1. Which is larger? F1x = F1 cos θ = 75 N cos 65= 31.7 N < 50 N = F2 So the box is going to end up moving to the left!!! So I’m going to make LEFT th ...

Modified Newtonian dynamics
In physics, modified Newtonian dynamics (MOND) is a theory that proposes a modification of Newton's laws to account for observed properties of galaxies. Created in 1983 by Israeli physicist Mordehai Milgrom, the theory's original motivation was to explain the fact that the velocities of stars in galaxies were observed to be larger than expected based on Newtonian mechanics. Milgrom noted that this discrepancy could be resolved if the gravitational force experienced by a star in the outer regions of a galaxy was proportional to the square of its centripetal acceleration (as opposed to the centripetal acceleration itself, as in Newton's Second Law), or alternatively if gravitational force came to vary inversely with radius (as opposed to the inverse square of the radius, as in Newton's Law of Gravity). In MOND, violation of Newton's Laws occurs at extremely small accelerations, characteristic of galaxies yet far below anything typically encountered in the Solar System or on Earth.MOND is an example of a class of theories known as modified gravity, and is an alternative to the hypothesis that the dynamics of galaxies are determined by massive, invisible dark matter halos. Since Milgrom's original proposal, MOND has successfully predicted a variety of galactic phenomena that are difficult to understand from a dark matter perspective. However, MOND and its generalisations do not adequately account for observed properties of galaxy clusters, and no satisfactory cosmological model has been constructed from the theory.
