Key Questions:

1. What is distance a measure of?
   • How far an object moves in any direction.
2. Is speed a vector or a scalar quantity and why?
   • Speed is a scalar quantity as it only has a magnitude (size) and not a direction.
3. Is distance a vector or scalar quantity and why?
   • Distance is a scalar quanity as it only has a magnitude (size) and not a direction.
4. Is the speed of a moving object normally constant?
   • No, when people walk, run or travel in a car their speed is constantly changing.
5. What is displacement a meaure of?
   • Displacement is how far away an object is in a given direction.
6. What are the typical speeds and factors that affect the speeds of people walking, running and cycling?
   • Walking ? 1.5 m/s Running ? 3 m/s Cycling ? 6 m/s. Age, terrain, fitness, and distance travelled.
7. Is displacement a vector or scalar quantity and why?
   • Displacement is a vetor quanity as it only has a magnitude (size) and a direction.
8. Is the speed of sound normally constant?
   • No, it varies as does the wind.
9. What is the typical speed of sound in air?
   • The speed of sound in air is 330 m/s.
10. What is the equation used to calculate the distance travelled and what are the units involved?
    • The equation used to calculate the distance travelled is: distance travelled = speed ? time s = v t distance, s, in metres, m speed, v, in metres per second, m/s time, t, in seconds, s
11. What is the equation used to calculate the average speed for non-uniform motion?
    • Average speed = Total distance / total time taken
