Study Notes
Speed
- Speed is the distance an object travels in a specific time.
- The formula for speed is: Speed = Distance / Time
- SI unit for speed is m/s, others include km/h, kph, m/min and mi/h.
- Examples of speed calculations are provided.
Velocity
- Velocity is the speed of an object, including its direction.
- The formula for velocity is: Velocity = Displacement / Time Interval
- SI unit for velocity is m/s. Velocity includes a direction (e.g., 10 m/s north).
- Examples of velocity calculations and determining which values are velocities are shown.
Examples
- Various examples of calculating speed and velocity are given, encompassing different scenarios like a person running, a car traveling, and a rocket moving.
- These examples include detailed steps to solve problems involving speed and velocity calculation. Corresponding solutions and answers are also presented.
