Study Notes
Computer Basics
- Computer information is stored in bits (0s and 1s)
- 1 nibble is equal to 4 bits
- 1 byte is equal to 8 bits
- 1 Kilobyte (KB) is equal to 1024 bytes
- 1 Megabyte (MB) is equal to 1024 KB
- 1 Gigabyte (GB) is equal to 1024 MB
- 1 Terabyte (TB) is equal to 1024 GB
- 1 Petabyte (PB) is equal to 1024 TB
- 1 Exabyte (EB) is equal to 1024 PB
- 1 Zettabyte (ZB) is equal to 1024 EB
- 1 Yottabyte (YB) is equal to 1024 ZB
- Operating system is a software that acts as an interface between user and computer hardware
- Processor speed is measured in megahertz (MHz) and gigahertz (GHz)
Motion in Physics
- Motion is a fundamental concept in physics
- Everything in the universe moves, even if it appears to be standing still
- An object is said to be in motion if its position changes with time
- Motion can be relative to different reference systems
- There are two branches of physics that examine motion: kinematics and dynamics
- Kinematics describes the motion of objects without looking at the cause
- Dynamics relates motion to the forces that cause it
Point Objects and Reference Systems
- A point object is an object whose size is very small compared to the distance it covers
- A reference system is a coordinate system attached to a point, used to describe the motion of a particle
- The reference system is usually chosen to be attached to the Earth
Types of Motion and Displacement
- Motion can be classified into one-dimensional, two-dimensional, and three-dimensional motion
- One-dimensional motion occurs when a particle moves along a straight line or path
- Two-dimensional motion occurs when a particle moves in a plane
- Three-dimensional motion occurs when a particle moves in space
- Displacement is the change in position of a particle in a particular direction during a given time
- Displacement is a vector drawn from the initial position to the final position of a particle
