Ramp Lift
11. What principle was used to make it easier to lift the object to specific height in the ramp lab?
answers? best answer is its right!
you did not describe the ramp lab....
so just guessing, but the answer must be "mechanical advantage".
i.e. was there a pulley system in the ramp lab?
or a lever and/or fulcrum of some sort?
those things provide mechanical advantage. this is a factor (>1) by which a mechanism multiplies the force put into it, hence increasing the work that can be done by a fixed amount of force...
cheers
