Study Notes
- Force is a physical phenomenon that causes an object to move or change direction.
- Newtons is the unit of measurement for force, named after English scientist Sir Isaac Newton.
- Force can make an object move, change direction, speed up, stop, and change shape.
- Contact force requires objects to touch each other to function, such as opening a door, kicking a ball, or pressing a button.
- Non-contact force occurs without objects touching, including magnetic force, electrostatic force, and gravitational force.
- Magnetic force is a push or pull exerted by a magnet, capable of attracting magnetic objects.
- Electrostatic force exists between charged particles, resulting in phenomena like lightning and hair standing on end.
- Gravitational force is the force that attracts objects towards the earth's center, causing the moon, planets, and even water to move accordingly.
