Kinematics
Which of the following is a scalar quantity?
A car travels 40 km north and then 30 km south. Identify the quantities given in the scenario as scalars or vectors.
A hiker walks 5 km east, then 3 km north, then 2 km west. Which values are scalars and which are vectors? Justify your answer.
What does the length of an arrow representing a vector indicate?
In one-dimensional motion, what does a negative sign in front of a vector quantity indicate?
A car is traveling east at 20 m/s. Represent the car's velocity as a vector. If east is considered the positive direction, how would you represent this velocity using vector notation in one dimension?
A car moves 10 m to the right, then 5 m to the left. What is the resultant displacement?

An object moves 20 m east, then 15 m west, and then 10 m east again. What is the object's total displacement?
A person walks 3 km north, then 4 km west, then 2 km south, and finally 1 km east. Calculate the total displacement, considering both magnitude and direction, and explain the steps to arrive at the answer.
A student walks 5 meters east and then 5 meters west. What is the total distance the student traveled?
