Year 7 Physics keywords

2. When a force moves something over a distance (Work = Force × Distance).
5. When light bends as it passes from one material to another.
6. The amount of force on a certain area (Pressure = Force ÷ Area).
8. The energy something has because it is moving.
9. How quickly work is done or energy is used (Power = Work ÷ Time).
10. The amount of space an object takes up.
13. The force of gravity acting on an object’s mass, measured in newtons (N).
16. Vibrations that travel through air (or another medium) and can be heard.
17. How fast something is moving, calculated by distance divided by time.
18. A force that pulls objects toward each other, especially toward the centre of the Earth.
19. How much mass is packed into a certain volume (Density = Mass ÷ Volume).

1. A force that slows things down when two surfaces rub against each other.
3. When light bounces off a surface.
4. The amount of matter in an object, measured in kilograms (kg).
7. How quickly an object changes speed.
10. A rapid back-and-forth movement that produces sound.
11. A form of energy that travels in straight lines and lets us see things.
12. A push or a pull that can make an object move, stop, or change direction.
14. Stored energy that an object has because of its position or shape.
15. The ability to do work or cause change; comes in many forms like heat, light, or movement.
