Quick explanation
Define speed as distance travelled per unit time
- This point belongs to Forces and motion, especially Distance, displacement, speed and velocity.
- You need to be able to define speed as distance travelled per unit time.
- The key ideas to know are speed and distance.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Distance, displacement, speed and velocity to exam-style questions, flashcards, and revision notes for Forces and motion.
Quick student answer
What is speed?
Direct answer
In Physics, this page helps you answer questions about speed within Forces and motion. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Speed and Distance.
Key terms
- Speed: The distance travelled per unit time, typically measured in metres per second (m/s).
- Distance: The total length of the path travelled by an object, regardless of direction.
Common trap
Misunderstanding Speed Definition: Emphasize that speed is a scalar quantity that only considers distance travelled over time, while velocity is a vector quantity that includes direction.
