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?
