Question
Define speed in terms of distance and time.
Answer
Speed is defined as the distance travelled per unit time. It quantifies how fast an object is moving, typically expressed in meters per second (m/s).
Explanation
This question tests the student's understanding of the basic definition of speed, a fundamental concept in physics related to motion. A clear definition shows comprehension of the relationship between distance and time.
Common mistake
Misunderstanding Speed Definition
Students often confuse speed with velocity, thinking they are the same because both involve distance and time.
Emphasize that speed is a scalar quantity that only considers distance travelled over time, while velocity is a vector quantity that includes direction.
