1. A scalar is a quantity with only size, no direction. 2. Total time from A to D is the sum of the time for each part of the walk. 3. Total distance from A to D is the sum of the distances walked in each part. 4. Draw vectors for each part of the walk using the tail-to-head method, then measure the displacement vector's length on the diagram and convert it to meters using the scale. 5. Average speed is total distance divided by total time. 6. Convert the speed from meters per second to kilometers per hour by multiplying by 3.6. 7. The magnitude of average velocity is LESS THAN the average speed. 8. This is because average speed considers the total path length, while average velocity only considers the straight-line distance between the start and end points. 9. Displacement is the straight-line distance and direction from the starting point to the ending point.

To understand scalars a bit more, think of them as the straightforward friends of the physics world. Scalars only have magnitude, which means they can be represented by a single number with a unit (like 5 meters or 30 seconds), but they don’t care about direction. This simplicity makes scalars essential in calculations involving temperature, mass, and time, where direction just doesn’t play a role! Now, when we look at displacement, it’s the superstar of the position world, combining both distance and direction. It’s defined as the shortest distance from the initial point to the final point, often represented as a straight line with a specific direction. So, if you walked in a big loop, your distance could be much greater than your displacement, which remains the straight-line distance between your starting and ending points. This means that while you might have taken a long scenic route, your displacement would just reflect your net change in position!
