  • A simple derivation of the Centripetal Acceleration Formula?
    Could someone show me a simple and intuitive derivation of the Centripetal Acceleration Formula $a=v^2 r$, preferably one that does not involve calculus or advanced
  • kinematics - Why are there seemingly two conflicting equations for . . .
    Equations 1 and 2 are valid only for constant acceleration Equation 3 is valid only for constant velocity Constant acceleration (if nonzero) and constant velocity are incompatible conditions, so combining 2 and 3 produces nonsense
  • Is acceleration $a = s t^2$, or $a = 2s t^2$, or something third?
    Acceleration is defined as $ a = \frac {s} {t^2} $ Distance can be calculated as the area under velocity-time line; given a constant accelation, and an initial velocity of 0, this forms a triangle: $ s = \frac {at^2} {2} $ The latter, though, gives me the definition $ a = \frac {2s} {t^2}$ Is the former, then, wrong?
  • Why is $F=ma$? Is there a straightforward reason?
    A spring, stretched by a constant amount, causes the velocity of the object to change linearly with time - the acceleration produced in a given object by a given force is constant If a second spring, identical with the first stretched by the same amount, is used side by side with the first, the acceleration is doubled
  • Calculate max velocity given time, distance and acceleration
    Solution : (Graphical) The question of max velocity becomes the question of attaining the max height on the graph you posted while keeping the area under the graph and the slope constant since the distance and acceleration are fixed
  • Does force cause acceleration or acceleration cause force?
    Newton's equation defines the relationship between force and acceleration (or, strictly, between force and change of motion); it doesn't define force itself (though, as Wikipedia notes, it's sometimes presented like that)
  • integration with respect to time - Mathematics Stack Exchange
    Shortly, I want to solve initial theta and phi velocoties so that the particle stays on the 'surface of sphere' while orbiting center mass under potential (i e Newtonian) This also means that the 'r' (radial) acceleration and velocities are zero as the distance r stays constant (radius of sphere)
  • Distance formula using initial velocity and acceleration
    Distance formula using initial velocity and acceleration Ask Question Asked 10 years, 2 months ago Modified 2 years, 7 months ago
  • What is angular frequency and its physical significance?
    They did mention, though, that it's called the angular frequency and showed that it is dimensionally correct to put it ($\omega^2$) in the equation But there's no explanation what is it actually and where it came from They'd tried explaining it by relating it to angular motion, but it made it worse, I don't see how angular motion is relevant
