๐ Motion: Speed, Velocity, and Acceleration
This quiz explores the fundamental concepts of motion, including how to calculate and distinguish between speed, velocity, and acceleration. **What you'll learn:** - Define and calculate speed and velocity from distance and time data - Distinguish between scalar and vector quantities in motion - Understand acceleration as the rate of change of velocity - Apply motion equations to real-world scenarios - Interpret motion graphs and extract information about moving objects
