Study Notes
Speed
- Speed is how fast something moves, showing distance covered in a given time.
- Measured in units like meters per second (m/s) or kilometers per hour (km/h).
Distance
- Distance is the total length of the path traveled.
- Measured in units like meters (m) or kilometers (km).
Time
- Time is the duration of movement.
- Measured in seconds (s), minutes (min), or hours (h).
Speed Calculation
- Speed is calculated by dividing distance by time.
- Formula: Speed = Distance / Time
Average Speed
- Average speed is the total distance divided by the total time.
- It represents the overall speed, considering variations in speed during a period.
- Formula: Average Speed = Total Distance / Total Time
Examples
- A car traveling 100 km in 2 hours has a speed of 50 km/h.
- A runner completing a 400-meter track in 50 seconds has an average speed of 8 m/s.
