Physics Concepts
Key Terms:
1.Pressure - force per unit square
2. One-way valves - a basic squirt pistol consists of a tiny rubber ball that rests neatly inside a small seal
3. Reservoir - a place where something (as water) is kept in store
4. Piston - a sliding piece that receives and transmits motion usually inside a cylinder
5. Downstroke - the piston pushing in
6. Upstroke - the spring pushing the piston back out
7. Duration - the length of time something lasts
8. Equilibrium - state of balance
9. Compression - to squeeze together
Key Concepts:
1. How fast does water travel out of the water gun?
2. How is pressure used in a water gun?
3. What are you actually doing when you squeeze the trigger?
4. How does the water decelerate coming out of the water gun?
