Study Notes
Contact Force
- A force that acts on an object when it is physically touching another object.
- Example: Pushing a box, pulling a rope, hitting a ball.
- The force is transmitted through direct contact.
Non-Contact Force
- A force that acts on an object without any physical contact between the objects.
- Example: Gravity, magnetism, and electrostatic forces.
- The force acts across a distance.
Gravity
- A force of attraction between any two objects with mass.
- The strength of the force depends on the masses of the objects and the distance between them.
- The Earth's gravity pulls objects towards its center, causing them to fall.
Magnetism
- A force of attraction or repulsion between magnetic materials.
- Magnetic materials include iron, nickel, and cobalt.
- Magnetic forces can act across a distance.
Electrostatic Force
- A force of attraction or repulsion between charged particles.
- Charges can be positive or negative.
- Like charges repel each other, while opposite charges attract.
- Electrostatic forces can act across a distance.
Attract
- A force that pulls two objects together.
- Examples include the attraction between a magnet and a piece of iron, or the attraction between positively charged objects and negatively charged objects.
Repel
- A force pushing two objects apart.
- Examples include two like magnetic poles, or two positively charged objects pushing away from each other.
