Hydraulic Syringes Multiply Force

Motion/force differs depending on piston sizes.

Teaching & key ideas

What you do: Connect filled syringes and push small vs large piston. What students see: Motion/force differs depending on piston sizes. Why it works: Pressure transmits through liquid; force depends on piston area. Question to ask: Which syringe gives more force and which gives more motion?
