- 3. store — An object’s capacity to hold energy-the eight energy stores are kinetic, gravitational potential, chemical,
- 6. — The electricity generated by falling or flowing water, also called hydroelectric power
- 7. elastic potential, vibration, nuclear and electromagnetic
- 8. test — An investigation where all things are kept the same apart from one thing, called the independent variable
- 10. forces — Forces acting on an object that are equal in size but act in opposite directions, resulting in no change in motion
- 13. — The rate at which the velocity of an object decreases over time, or the rate at which something slows
- 15. — A push or pull that causes an object to change its motion (that is, start moving, stop moving or change direction)
- 16. — The requirements a design has to meet to be successful
- 17. — A machine that generates an electric current by moving a coil of wire inside a magnetic field, causing a current to flow
Down
- 1. — The rate at which velocity of an object changes over time
- 2. resistance — A force that acts in the opposite direction to an object moving through the air
- 4. force
- 5. variable — Something that remains constant and unchanged in an investigation
- 6. tide — The tide when the sea or river water level is at its highest
- 8. — A force created between two surfaces when they rub together-friction always slows the two objects down
- 9. meter — A unit of volume used to calculate the capacity of an object or space
- 11. — A type of magnet in which the magnetic field is produced by an electric current
- 12. — A scientific idea that states that an object at rest or in motion in a straight line, unless it is affected by an

- 15. — A deep, narrow, and long body of water, with steep land on its sides
- 16. — A limit or restriction on a design
