case study Questions
1. Average velocity is the ratio of total displacement to total time. Its direction is the same as the direction of
the moving object. Even if the object is slowing down, and the magnitude of the velocity is decreasing, its
direction would be still the same as the direction in which the object is moving. The magnitude of average
velocity is always less than or equal to the average speed because displacement is always smaller than or equal
to distance

Answers
1.The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.
2. meters per second

4. No. Velocity is a vector, and speed is the magnitude of the velocity vector. As a magnitude, speed can never be negative, and therefore a zero average speed directly implies a constant zero speed. Constant zero speed means constant zero magnitude, and hence the velocity must be a constant zero vector.
5.Average speed takes distance, that is total length travelled while being measured, while average velocity takes displacement, that is the straight distance from the original position to the final position.
