No, they are not combined. Force and acceleration are two distinct things and they are very much kept separate. The terminology is...

Instead of using those vague terms you should learn the simple formulas, and apply them.

This lies at the root of your misunderstanding. Gravity is the name we give to the phenomenon. There's gravitational force and...

I know what you mean. ##g## always has a magnitude of 9.8 m/s2 but objects don't always accelerate at this rate, they have to be in free...

Did you watch the movie October Sky? Don't remember for sure but think they witnessed it. Maybe it was fictionalized.

No it doesn't! Gravity tends to move things closer together, because the gravitational force is always attractive. Part of your...

Thank you very much for all the help and explanation kuruman, jbriggs444, Lnewqban, Herman Trivilino, Gavran, haruspex

That's the only way to do it! After all, the 3 m height of the poles has no effect on the distance from the top.

Start with a free-body diagram of the point where the 25 kg object hangs from the nylon rope.

its in the first picture. all the way to the right. :)

Can you show us that calculation? Or at least the value of the force?

Mechanical energy is conserved only if the collision is perfectly elastic. There is no change in temperature. Is that the same thing as...

Usually it's the ratio of speed after to speed before.

I would advise against writing the equation this way as it can introduce sign errors and it doesn't generalize easily to a situation...

My guess would be an almost definite "yes". Air conditioning techs deal with "high voltage" circuits connected to the mains that power...
