Study Notes
Distance
- Distance: The total amount of space an object has covered during its motion.
- It's a scalar quantity, meaning it only has magnitude (size).
- It's always positive or zero.
- Measured in units like meters, kilometers, or miles.
Displacement
- Displacement: The overall change in position of an object from start to finish.
- It's a vector quantity, meaning it has both magnitude and direction.
- It can be positive, negative, or zero.
- Measured in units like meters, kilometers, or miles.
Example Calculations
-
Visual Example 1: A car travels 25 km to a hill, then 10 km down a hill to another town.
- Distance: 25 km + 10 km = 35 km
- Displacement: Depends on the direction, could be 15 km, could be 35 km, or could be 0 km, depending on the start and end points.
-
Visual Example 2: Tim walks 5 meters, then 4 meters sideways to the bushes, then 3 meters towards the school
- Distance = 5m + 4m + 3m = 12m
- Displacement: Depends on position from the start and end points. A direct line drawing could give you a better idea about displacement
