Question
Define speed and explain how it differs from velocity.
Answer
Speed is defined as the distance traveled per unit time, while velocity is speed in a specific direction. The key difference is that speed is a scalar quantity, whereas velocity is a vector quantity that includes direction.
Explanation
This question assesses students' understanding of fundamental concepts in motion. It requires them to recall definitions and distinguish between scalar and vector quantities.
Common mistake
Misunderstanding the Distance Equation
Students often confuse the equation distance = speed x time, thinking that speed can be added to distance instead of multiplied.
To fix this, students should practice using the equation correctly by substituting values for speed and time, ensuring they multiply these values to find the correct distance.
