I have to design a lab to support that F=ma. we are using masses and pulleys but i'm not sure how to set this experiment up. anyone got any ideas?
thanks in advance 4 any help u can give me

There arte many posibel experiments with masses and pullys. But a lot of thm are about the efects of friction. A very simpel ekperiment might be just conecting 2 hanging masses over a pully and masure how much time passes until the havyer on reaches the ground. This should ofcourse be tasted with many diffrent masses on both sides.

By the way wathever experimet you set up it's usualy a good idea to use gravity as a form of acceleration. It is constant and you can easily control its size with a slide (the lass friction the beather).

Just take a general physics book full of exercises like Tipler. The most simple is the known as Atwood's machine: a pully with two masses.
