📚 Topic Summary
Constant velocity describes motion where an object moves in a straight line at a steady speed. This means the object's speed and direction remain unchanged throughout its movement. Understanding constant velocity is crucial for grasping more complex motion concepts in physics, such as acceleration. A simple kinematic equation, $v = \frac{\Delta x}{\Delta t}$, where $v$ is velocity, $\Delta x$ is displacement, and $\Delta t$ is the change in time, perfectly describes this type of motion.

✍️ Part B: Fill in the Blanks
Complete the following paragraph with the correct terms:
When an object moves with __________ velocity, its speed and __________ remain the same. The __________ is the change in position, and we measure how long it takes using __________. We can use the equation $v = \frac{\Delta x}{\Delta t}$ to understand the relationship between these __________.
🤔 Part C: Critical Thinking
Imagine a car traveling at a constant velocity of 20 m/s. How would a graph of its position vs. time look? Explain how the slope of the graph relates to the car's velocity.
