How can Newtonian gravity be converted to m/s without prefix?

AI Thread Summary
Fgrav, calculated using the formula Fgrav=(GMm)/(r^2), is expressed in Newtons. To convert this force into acceleration, one can apply Newton's second law, F=ma, leading to the acceleration due to gravity as a=F/m. This results in a gravitational acceleration of a_gravity=GM/r^2, which is measured in m/s^2. It's important to note that gravity itself is a force, not directly a velocity, hence the conversion to m/s is not applicable. Understanding these relationships clarifies how gravitational force translates to acceleration.

Before I inundate you with various elementary problems I'm facing, I need help with the concept.

Fgrav=(GMm)/(r^2)

So Fgrav is in units of Newtons, correct? How would one convert that to m/s?

Gravity is just a force an object with mass experiences, which can be translated to acceleration with Newton's 2nd Law, F=ma. It has nothing to do with velocity (which has units m/s). However you can turn it into units of m/s^2, which is the units of acceleration with the above mentioned law: a=F/m, therefore:
<br /> a_{gravity}=\frac{GM}{r^2}<br />

Where M is the mass of the object that is creating the gravitational field, not the "accelerating object".

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
