Forces and Their Types Quiz

Study Notes

Forces

A push or pull in a particular direction
Measured in Newtons (N)
Forces act in pairs
Forces usually cannot be seen, but their effects can
Forces have magnitude and direction

Types of Forces

Contact Forces - occur when two objects are in physical contact.
- Friction - Opposes motion between two surfaces in contact.
  - Amount of friction depends on the types of surfaces and how hard they are pressing against each other.
  - Example: Sliding down a slide
- Tension- Transmitted through a string, rope, cable, or wire when pulled tight from both ends.
  - Example: Tire swing hanging from a tree.
- Normal - Support force exerted on an object in contact with a stable object.
  - Example: Book sitting on a table, a person leaning against a wall.
- Applied - Force applied by a person or another object.
  - Example: Pushing a lawnmower.
- Spring - Force exerted by a compressed or stretched spring on an attached object.
Distance Forces - Occur when two objects are NOT in physical contact, yet exert a push or pull.
- Gravitational
- Electrical
- Magnetic

Examples of Forces

Air Resistance - Frictional force that acts on objects traveling through the air.
- Usually measurable at high speeds.
- Example: Air slowing a parachute as it falls from a plane.

Description

Test your knowledge on the various types of forces and their characteristics. This quiz covers contact forces like friction, tension, and normal force, as well as applied and spring forces. Understand how these forces interact and their effects on motion.
