Kinematics Quiz

What is the primary difference between distance and displacement?

• Distance includes direction, while displacement does not
• Distance is a vector, while displacement is a scalar
• Distance is the total ground covered, while displacement is the shortest path from start to finish
• Distance is measured in meters, while displacement is measured in kilometers
