We are learning about pulleys. Two types of pulleys we experimented with today were

pSingle-fixed-pulley system.

p“Single” refers to ONE pulley wheel.

p“Fixed” means ATTACHED.

pA single-fixed-pulley system uses a pulley with one wheel, and it is attached to something high, in this case a binder clip on a half-meter stick

 

pIn a movable-pulley system the pulley moves with the load.
