PULLEYS

Pulleys make work easier to do...or not

Do you remember the difference of pulling from a single fixed pulley or a complex movable pulley?

These videos will help you undesrtand it a bit better.

                                                                                

                                                                          

These are some of  the experimental activities we did in class to understand the way pulleys work.
