Study Notes
- Position is where something is located.
- Words to describe position: inside, under, left, right, on top of, besides, between, behind and next to
- A reference point determines if something is in motion.
- Distance is the space between items or locations.
- Distance is measured in centimeters, meters, and kilometers
- Tools for measuring distance: ruler, meter stick, tape measure.
- Force can change an object's direction, position, speed, or stop it.
- Force: a push or pull causing movement or change.
- Pull force brings an object closer.
- Push force moves object away.
Force of Water
- Water can move things.
- Water flowing in a river can move rocks and branches.
- Splashing water can push your hand away.
Force of Wind
- Wind can move things.
- Strong wind can make things move.
- Examples of wind force: blowing, moving leaves, flying kites.
Gravity
- Gravity moves objects toward Earth's center.
- Gravity pulls things together and keeps us on the ground and makes objects fall.
- A magnet attracts certain metals like iron.
Magnet Properties
- Magnets attract certain metals like iron, which is called attraction.
- Magnets repel when like poles face each other which is called repulsion
- Every magnet has a north and south pole, opposite poles attract.
- A magnetic field is the area around a magnet that can attract or repel magnetic materials.
- Permanent magnets keep magnetism, while temporary magnets lose it when the magnetic source is removed.
Magnetism
- Magnetism is the ability to push or pull objects with magnetic properties.
- Magnets exert force on metals such as iron, cobalt, and nickel.
- Magnetic materials are attracted to magnets, usually metals like iron, nickel, or cobalt.
- Non-magnetic materials, such as plastic, wood, or glass, are not attracted to magnets.
Uses of Magnets
- Compasses use magnets to indicate direction.
- Strong magnets are used to lift objects.
- Generators and motors use magnets.
- Magnets are used for data storage in computers.
- Medical equipment like MRI uses magnets to create internal body images for diagnosis.
