Module Notes: Speed and Velocity Basics

Key Concepts: Speed and Velocity

• Definition of Speed/Velocity: The fundamental concept of speed or velocity is defined as the distance traveled over a certain period of time. It quantifies how quickly an object is moving.
  • Formula: Mathematically, this can be expressed as: \text{Speed} = \frac{\text{Distance Traveled}}{\text{Time Taken}}
  • Distinction: While often used interchangeably in common language, in physics, speed refers to the magnitude of motion (e.g., 60 \text{ mph}), whereas velocity includes both magnitude and direction (e.g., 60 \text{ mph} North).

Demonstration Setup and Mechanics

• Objective: The concept of speed and velocity is likely being demonstrated through a practical experiment or observation, which students may have experienced personally.
• Components of the Demonstration: The setup involves several distinct elements:
  • A spinning ball.
  • A ramp.
  • A couple of additional balls.
• Operation of "Spinning Things": Specific mechanisms for the
