Question

Please write in paragraph form about atleast two physics principles (from two different phyics units) that the Water Rocket uses to operate as a toy (this is for a presentation).

Answer 1

Water Rockets basically use two physics principles. The first one is that the air flows from high pressure to low pressure and the second one is that for every action, there is an equal and opposite reaction whichn is Newton's third law.

We fill the water rocket with some water and with some highly pressurerized air (Unit = Pascal). When we release water rocket from it's initial position the pressurized air throws water outside with relatively small nozel then newton's third law takes places because (Unit = Newton) there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
