Physics

2. The force applied to a certain area. It can be high or low and can be measured in different units, like pounds per square inch.
3. How much matter (stuff) is packed into a certain space. It can determine whether something floats or sinks in water.
7. A push or a pull that can make objects move, stop, or change direction.
8. An object that can attract certain materials, like iron or steel. It has two ends, called poles, called North and South.
9. The force that happens when two things rub against each other and try to slow down or stop each other's motion.
10. A form of energy that can flow through wires and power devices. It can also create light, heat, and sound.
12. The ability to do work or make things happen. It can come in many forms, such as light, heat, or motion.
13. The force that attracts certain materials, like iron, towards magnets. It can also push or pull other magnets.
15. The speed of an object in a specific direction. It tells us how fast and in which way something is moving.
16. A region around a planet where its magnetic field interacts with charged particles from space, like the solar wind.

1. How fast an object's speed changes over time. It can speed up, slow down, or change direction.
4. The tendency of an object to resist changes in its motion. It likes to keep doing what it's already doing, either moving or staying still.
5. The act of moving or changing position. It can be fast or slow, straight or curved, and in different directions.
6. The force that pulls objects towards each other, like how Earth pulls everything towards its center.
11. A type of energy that lets us see things. It travels in straight lines and can be reflected or refracted.
14. Vibrations that travel through the air or other materials and can be heard by our ears.
